Community Blog | How to: Seated Measurements for All Types of Bottoms (i.e., for wheelchair users) with Lolie

Hello, Lolie here (@lolieya on IG)! I am here today to show you my process to get measurements for panties that fit well for the permanent seated position, meaning for wheelchair users — but anyone that sits is welcome! You could use this tutorial for any kind of bottoms, but we’ll be focusing on underwear. I’ve been a full-time wheelchair user for 4 years now and getting panties/pants/bottoms that fit have been close to impossible. Let me guide you as to why and show you some solutions I’ve found.

Bottoms are complicated to fit for wheelchair users because we traditionally fit bottoms standing up. Every single book, tutorials, YouTube videos and blog posts on fitting seems to approach it that way. But since wheelchair users are not standing upright … it’s not useful for our fitting purposes. If each time someone would present a fitting problem with a picture, it were shown seated too, that would help to identify which existing technique would be best to improve the fit of the pattern. The same problem shown standing or seated will just not look the same, so it’s hard to draw parallels between them without being shown what it looks like.

The final result

Also, fitting bottoms for the seated position isn’t easy. We’re creating a different shape altogether, so we need, for example, to add shaping at the knee, elongate the rise in the back, shorten it in the front, elongate the inseam (pants will ride up), add shaping to the side seam at the hip level … The trickiest part, in my opinion, being to remove the shaped excess where the legs meet the torso at a 90 degree angle.

But for now, we’ll focus on the top part with panties. We’ll of course need appropriate crotch depth, crotch rise measurements, waist and hips and waist to hips, taken seated. Taking seated measurements is also good for anyone to ensure that, when choosing a size in a close fitting garment, you’ll end up with enough room to sit comfortably. 

In 2016, just before I had to start using my wheelchair all day long, I had just drafted a panties block for myself, and they fitted very well. I loved them and made a ton. They were medium-high rise, bikini style (low cut on the legs), really regular panties just like I personally like them. This pattern was literally drafted for me.

However, when I tried them again recently, they didn’t fit at all anymore. I had lots of excess fabric in the front (they went higher than my rib cage) and they were short in the back. Also, even if my measurements  were very similar, my body shape had changed a bit because of the year I spent in a hospital bed. My abdominal muscles were making themselves scarce, which tends to make the belly protrude. So, I had to go back to the drawing board on a quest for a comfortable pair of panties pattern once again!

Let me show you both patterns on top of each other so you have an idea of the difference. It’s impressive. It was drafted for the same person, with the same weight, the only difference is being seated vs standing.

The pattern on the bottom is the new one and the one in two pieces, off-white, is the old one.

At first, I thought I’d just get my lingerie pattern drafting book and make another pattern with my new measurements. But it didn’t work because I didn’t know how to properly measure myself while seated. I was at an impasse, as I searched the internet on how to take those measurements, and couldn’t find much (hence why I’m writing this).

Eventually, I came across Apostrophe Patterns and their MyFit Underwear pattern generator. It generates a pattern based on a number of personal measurements you input in the system. Once you purchase a pattern, you can generate as many variations as you desire, so I thought it was a safe bet. The pattern has many options, and thorough instructions. There is also a maternity option which would make it simple to tilt the waist forward, but most of the time these options offered will cover the belly and make a bigger waistband, which is not what we want, so I preferred to go with only measurements.

To take the measurements, you will need two strings/piece of lingerie elastic long enough to go around you, scotch tape (any kind), a wooden stool, a mirror, two rulers or one ruler and something very thin and straight.

First, for the crotch depth:

  1. Sit on a flat and hard surface, preferably a stool, to see all around easily, or adapt to your needs.
  2. Put a string (light blue) around your waist, in exactly the same place where you want your waistband to hit, and tape in place (orange). It’s very important to be as precise as possible about this.
  3. Your waist placement doesn’t have to be parallel to the floor, if that’s your preference.
  4. Take a big ruler and place it between your thighs, one end perfectly flat on the stool.
  5. Take the other ruler (or any straight object) and place it at the same height as of your waist string and perpendicular to the first ruler. Mark where they cross. This is your front crotch depth measurement. 
  6. Do the exact same but in the back, asking for help if needed so the rulers stay at a 90 degree angle to each other.

Tip: you can use a clip to mark where the rulers intersect so it’s easier to read.

The administrators on Apostrophe Patterns page suggested adding 1,5cm (0.5″) to the back rise and subtracting 3,5cm (1.5″) from the front depth, so I suggest the same to you. This method gave me great results.

Example:

Let’s say I have identified a front crotch depth of 21,5cm (8.5″) and a back depth of 21cm (8.25″): 

Front: 21,5 – 3,5 = 18 cm (8.5 – 1.5 = 7″)

Back: 21 + 1,5 = 22,5 (8.25 + 0.5 = 8.75″)

For the rise, stay in the same position. You will need to use a flexible tape measure. 

  1. Put the flexible tape (light beige) between your legs, as shown in the picture.
  2. For this measure, it’s useful to have at least three clips (hot pink) and string or elastic (light blue) on your chosen waist placement, well taped in place (orange).
  3. Clip one end of the tape measure onto the string.
  4. Put another clip on the tape measure where you want your inseam to be (the seam from hem to hem inside of the legs).
  5. Finally, clip the tape with a third clip on the waist string in the back, making sure you don’t tug on anything in the process. It’s supposed to be snug but not tight. Adjust if necessary by looking in the mirror.
  6. Once done, take the tape measure off while keeping the clips in place and note the measurements. Don’t mix up the front and back!

Now, our last step is to take our hip, waist and waist-to-hip measurements seated. 

For the waist, just take the measure on top of the blue string, while seated. It doesn’t matter if your waistline is tilted for this. I have no pictures as it’s pretty self explanatory.

For the hips, it is not complicated. 

  1. If possible, stand up and wrap the tape measure (light beige) around your hips, parallel to floor, making sure it’s in the widest part of your bum/hips. Tape it or hold it in place. 
  2. Just note that it will probably not be parallel anymore once you sit down and that’s ok.
  3. Sit down and let the tape expand around you to take the measurement. 

Tip: If you’re not able to stand, alternatively you can roll over in your bed, have someone tape the flexible tape measure on the widest part of your bum, transfer like usual, make sure the tape is still well placed and measure around yourself.

Waist-to-hip measurement

  1. Measure from your waist string to where your hip line (the tape measure) ended up on the side. 

Those are the measurements that I would start with and add in a pattern generator or use for pattern drafting instructions. Then, make a toile of your new pattern and adjust if necessary. Our bodies come in many different shapes, so there might still be some things to fit even if it was made to your own measurements. 

If you want to use an existing pattern, choose a your size according to the numbers you found, but know that it wasn’t drafted for someone sitting so there will be lots of other things to adjust. But with these and knowledge in pattern alterations, you can certainly do it. Trousers would be much more difficult than panties to adapt though.

About the MyFit Underwear pattern generator, if centimetres are not your jam, there’s the option to use both centimetres or inches in the pattern generator, so no need to worry! I usually use inches, except when I do pattern drafting. I find centimetres easier to calculate and more precise. 

And there you have it! Now, you only have to draft your underwear block using your preferred method or use a pattern generator system and toile your comfortable masterpiece!

Advanced Fitting Series with Designer Stitch | Contouring Gaping Armholes with Darts

Hi Ho my friends. Ann here from Designer Stitch and I am back with another fitting post in the Sew Busty fitting series – answering your questions about any fitting dilemmas or problems that you may encounter when sewing all of your fabulous me-made clothing.

And I bet you cannot even GUESS what I am going to talk about today?.

You guessed? – well YES – my favourite subject of all time. DARTS!!!

As you may know I have a huge love affair with darts. And all things DART related.

Darts are the ESSENTIAL fitting tools of a well made and well fitted garment.

So today I put on my My Teachers Hat 👩‍🎓 – this is what I call my how-to’s over in my Designer Stitch Pattern Support Group over on Facebook. Why not come over and say hello to us all. xx

What are Darts?

The above image – left – details the ABSOLUTE minimum of dart placement that you should have on a bodice. The minimum for fitting – and I say MINIMUM for a reason – are the side bust darts. They help contour the garment – alleviate drag – and also stop the centre front of a garment lifting. 

The above image – right – are the minimum CONTOUR dart/wedgies that you would need to have if you were fitting a sleeveless garment with a lowered neck. These are called contour darts or wedgies – as they facilitate the contouring of the garment over and around your entire bust mound. 

The darts added to the armhole stop your garment gaping around the side bust mound. The darts added to the neckline stop the garment gaping as the bodice comes off its contour of the bust mound into the flat surface of your upper chest area.

But Why Darts?

The image on the left shows a side view and a straight piece of cloth. A body is 3 dimensional yet the cloth is 2 dimensional. 

When the cloth has to fold over the body it creates folds or wedgies on itself at its hinge points. So really the folds and wedgies it makes are just the DARTS that we need. The cloth tells us what it wants to do. 

What Happens When There are No Darts in Play?

A garment that has no darts in play will never EVER fit your body properly. And the above images are perfect examples of this.

Over on the Sew Busty Facebook Group our Anouska W posted the above pics asking for fitting advice. The image on the left shows massive gaping in the side armhole. It is quite obvious.

The fullness in this area creates a type of “wing” that can be contoured back into the bust mound with shaping. And what shaping do we use – well, DARTS OF COURSE!!

The image on the right shows that the toile that Anouska made is actually telling us what it wants to do. The fullness and folds of the fabric are showing us that it wants to fold down on itself – hence creating that all important contour – in the form of a dart. 

Two pattern pieces are shown side by side. A caption reads "The above are the pattern pieces used. While there is provision of a "full bust fit" the shape has been widened only. Not a single dart for shaping is to be seen anywhere on the patterns."

I asked Anouska to send me a pic of the pattern pieces that she used. As you can see above there are no darts to help contour the pattern piece around the body. There is a separate pattern piece provided for a “full bust” – but this has just been done by widening the pattern.

Not a single dart for shaping is to be seen anywhere on the pattern. 

Adding Contour Darts to Your Pattern Piece

Two pattern pieces are shown with darts added at the armscye and side seams. A caption reads "The minimum required for this pattern is a side bust dart regardless of the standard fit or full bust fit. Each fit must have its own dart sitting in the side seam. Then to facilitate shaping a contour wedge/dart should be taken in the armhole for bust mound shaping."

The absolute minimum required for this pattern should have been in the form of side bust darts regardless of standard fit or full bust fit.

Each fit must have its own side bust dart. And the full bust fit would have a bigger side bust dart than the standard fit.

Then to facilitate the shaping around the side bust that Anouska’s toile is telling us it needs – a contour dart/wedgie – should be then taken for side armhole bust mound shaping.

And you may ask – How much should this be ? The toile will tell you.

Whatever you have pinned out to create your new contour dart is the full dart value amount.

Pinning out shape on your toile is the best way to ascertain how much shaping is needed in any part of the fitting garment. 

An image of a pattern piece with side bust darts, diamond waist darts, and armscye darts is shown. A caption reads, "This is the front of my Raven cami. The armholes have already been controured as you can see from the angle of the side seam and the curve of the armhole. If any additional contouring is needed you draw your contour wedge in position that you pinned your toile out – draw it onto your pattern as if it was a new dart.

When adding your contour dart/wedgie to your pattern you must ensure that the dart is angled correctly – again your toile will tell you – and that it finishes its length at the bust apex point.

The above image is the front of my Raven Cami/Slip Dress pattern. I have already contoured my armholes with a fitting dart as you can see from the angle of the side seam and curve of the armhole.

If you need additional contouring you draw your contour dart/wedgie in position – as if it was a new dart – to the length to the apex.

An image of a camisole pattern with darts at the armscye, side seam, and diamond waist darts is shown. A caption reads: "The new contoured darts in the armhole can then be shortened back from the apex point – anywhere from 3 cms or more – or they can be pivoted back into the existing side bust dart. But a WARNING – do not pivot all of your contour darts into the side bust dart – making one big huge dart. If the dart is too big it will not sit correctly and you may end up with a massive pointed cone shape sitting off your side seams and your side bust mound. Bust darts DO NOT do all the work for fitting your body. Your body needs shaping over ALL of its contours.

For the final pattern you now have a few choices.

You can either leave your new armhole dart in place as it is – but if so you must shorten this new dart back away from the apex to avoid pointy “boobs.” They are usually shortened back a minimum of 3 cms (1 1/4″) but this will be dependent on how it sits on your body. It may need more length or even made shorter. See what the toile is doing and then make your final decision. 

Alternatively the armhole dart can be pivoted back into the existing side bust dart. But a HUGE WARNING!!! DO NOT – and I repeat DO NOT pivot all of your fitting darts into your side bust dart. I see countless blogs and YouTube instructional videos advising this – and it is so so wrong.

Pivoting all darts into a side bust dart not only results in one massive DART – but you will have a dart that doesn’t sit correctly and may end up with a HUGE pointed cone shape sitting off your side seams.

And one thing I HATE that makes my eyes scared – it is pointy BOOBS. 

Side bust darts should not – and DO NOT – do all the work for fitting your body.

Your body needs shaping over all of its contours.

Hence why darts are needed in key fitting areas. 

I hope that you have learnt something by reading my story and please shout out if you have any thoughts to share.

The good thing about sewing and fitting our bodies – we always learn NEW THINGS.

Love to you all and please stay safe and well everyone xx

Cheerio my lovelies

Full Bust Adjustment Guide | Sleeveless Princess Seam FBA

For Community Thursday this week, I’m doing something a little different and joining in the fun of a community sewing challenge! When Jess (@SoWhatIfISew) asked me to participate in her #SewNewInJune challenge, I KNEW this meant I needed to expand my horizons. I love sticking to my comfort zones: cotton poplin, patterns with built-in cup sizes, minimal pattern adjustments …

As you probably know I’m a pretty lazy sewist. I’m more here for the creative parts of sewing, like choosing which fabric to use with which pattern, than the technical parts. I suck at spatial reasoning, geometry, and math, and therefore I’m not the biggest fan of pattern adjustments.

But I knew #SewNewInJune meant I should do an full bust adjustment. I haven’t done an FBA in … probably a year. But here I am, running a blog called Sew Busty and being challenged by Jess to try new things.

So I chose an FBA that I’ve personally seen people struggle with: the sleeveless princess seamed full bust adjustment. And Sew Over It was kind enough to gift me the Rosie dress pattern to work my magic! (While Sew Over It is drafted for a D cup at larger sizes and offers cup options at all sizes in some of their patterns, the Rosie dress is drafted for a B cup at my size.)

While doing research for this, I discovered a couple of things:

One: It’s different enough from a traditional princess seam FBA that this alteration can be intimidating.

On a traditional princess seam full bust adjustment, you use the armscye as an anchor point, like in this tutorial from the Curvy Sewing Collective. But, on a sleeveless dress with princess seams, you don’t have a traditional armscye, but are instead altering part of the neckline, so it can feel a bit tricky. It’s honestly not that much different in practice, but it definitely feels different.

Two: Most full bust adjustment tutorials assume a small (1″ or so) full bust adjustment.

My bust certainly isn’t the biggest, but I need a 3.5″ total full bust adjustment, or 1.75″ on each side. This is much bigger than the 1/2″ on each side that most tutorials expect you to be doing. For example, I tried to follow this tutorial from Closet Core Patterns that was written for a dress with very similar lines to the Rosie, but unfortunately, it wasn’t cooperating with my large bust.

Sleeveless Princess Seam FBA Tutorial

Alright, LET’S GO!

choosing a base size

The first step is to figure out what base size you’ll be making. Choose based on your high bust + 2″ as the “bust” measurement on the chart. I’ve talked about this before, but most FBA tutorials will have you choose based on your high bust substituted for the size chart’s “bust” measurement. I’m honestly not sure why tutorials teach this way, as this instruction fails to consider that most patterns are drafted such that the high bust is 2″ smaller than the full bust.

Thus, if the high bust measurement is not offered on a pattern, you must add 2″ to your high bust measurement, and choose the size with a bust measurement that most closely corresponds to this HB+2. My high bust measurement is somewhere between 34.5 and 35 depending on the time of day/month, so I need a size with a bust measurement that is somewhere between 36.5 and 37″. On the Rosie, the size 12 has a 37″ bust, so I selected this base size. As a bonus, the size 12 also has a 30″ waist, which is very close to my 29.5″ waist.

The only place I didn’t match the size 12 (aside from my full bust, which we will get to …) is the hips, where I’m around a 37.5″. The size 12 accounts for a 40″ hip. BUT I decided not to grade the pattern down at the hip because the Rosie is designed to have a free-flowing skirt: The finished garment at size 12 has 86″ of fabric at the hips, meaning there’s 46″ of ease built in … what’s a few more inches of ease at that point?

Doing some full bust adjustment math

Now, to start our FBA, we must do a little math. As I mentioned, the Rosie is drafted for a 2″ full bust to upper bust difference. I have a 5.5″ difference. So I need to subtract 2 from 5.5, for a total of 3.5. Then, because you’re really working on half of your bodice, you need to divide this by 2. For me, 3.5/2=1.75, meaning I need to add 1.75″ on my bodice pattern.

Marking the apex and pivot points

Because the apex is not marked on the Rosie, you need to find it. On a princess seam, the apex is somewhat easy to find: It’s the place where the curve is largest. I marked this point on my side bodice:

You need to find the same point on the center front, which is a bit trickier. I did this by using my flexible ruler to measure down from the notch to the apex on my side bodice, then on my center front bodice:

Now, this point isn’t really the apex. The apex is really 5/8″ or 2 cm inward because of the seam allowance. This will mark your first pivot point. Mark this point and draw a line down, parallel to the seam line.

You can see in this picture that I drew my line parallel the grain line, not the seam line. This was a mistake. This is one of those times where you need to do as I say, not as I do. You’ll notice in later pictures that I went back and corrected myself. I just somehow forgot to go back and take a photo of the line marked correctly.

Now, you’ll want to draw a line from the apex to the first notch on the neckline. If your pattern does not have a notch here, choose a point an inch or two inward from the seam line.

You’ll also want to draw a line from the apex over to the side seam, about halfway between the notch and the armpit. Again, if you don’t have a notch, choose a point about a quarter of the way down the side seam.

Cutting your pivot lines

You’re now going to, very carefully, cut from the bottom of your bodice, up to the apex, then up to, but not through, the top notch. Leave a small bit of paper at the top notch so that your piece is still hanging together by a thread.

Similarly, cut from the side point to but not through the apex, again leaving this cut so it’s hanging together by a thread of paper.

You’ll see in this picture that I’ve corrected my line from apex to the bottom of my bodice, so it’s now following the seamline instead of the grainline. Yay!

adding width for large breasts

The next step in our princess seam large full bust adjustment is to tape the large side of your piece down to a spare piece of paper. Draw a line parallel to your cut line however many inches from your cut line that you determined you need for your full bust adjustment. In my case, this new line is 1.75″ from the cut piece:

Now, swivel your “hook” to match this line. This will open up a dart on the side seam of your piece. Don’t worry about that just yet. Tape down your “hook.”

Closing the Dart

Now, draw a line from the bottom of the dart you created to the apex point on the seam allowance (not just to the apex point where our cut marks are). On my bodice, this line is very close to the dart line – so much so that it’s hard to see. Yours may look much different, and that does not mean you’ve done anything wrong.

Tape down the bottom of your dart.

Now, cut from the curved side of your pattern piece through that line you drew, stopping at the apex point. Once again, cut to but not through this point.

Now, fold your dart closed. This will essentially move the dart from the side seam to the curved seam of your bodice.

You’ll now want to cut the “hook” piece at the lower notch, to cut the last several inches off. Move this downward to match the bottom of the larger part of your pattern piece, and fill in with scrap paper. Tape into place.

Tape this down, then draw a curve to connect the curved side of your bodice, as shown below. You can use a french curve for this or freehand. I personally freehanded this, even though I had my french curve next to me.

You also need to draw a slightly curved line to fill in the concave on your neckline/armpit area. Again, you can use a french curve to do this or you can choose to freehand it.

Dealing with the Waist

Now, obviously the problem with this full bust adjustment is that it has also added 1.75″ (or however many inches you did for your FBA) to our waistline, which I don’t personally want. The way to deal with this is to remove those same 1.75″ from the waistline.

Mark a dot however many inches inward from the side seam that you added for your FBA. If you added 3″, mark a dot 3″ in from the side seam. If you added 2.25″, mark a dot 2.25″ inward.

Using a french curve or freehanding, draw a gradual line roughly from the notch to the dot you just marked. You want this gradual line to start just below the bust line.

You’ll now cut along this line, and this will be your side seam. I know it looks weird as hell, but it’ll work out. I promise.

Now, I do want to mention that there’s some debate within the sewing community about where it’s best to take this excess. Some dressmakers suggest taking it from the princess seam rather than the side seam, and others suggest splitting this difference, taking some from the side seam and some from the princess seam. From my experiments in pattern drafting, this makes sense to me – the traditional approach in drafting is to distribute excess between multiple places, and when you add extra to one place (here, the princess seam), it also makes sense to remove it from that same place.

I’ve personally always taken the excess from the side seam, and I’ve been happy with the fit. I also note that every princess seam FBA tutorial I’ve seen (such as Curvy Sewing Collective, Megan Nielsen, Seamwork, Deer and Doe, In the Folds) does it this way. However, I’ve heard from some people with larger busts than me who have found this system to not work for them, and have found better success either removing the excess from the princess seam or half from the princess seam and half from the side seam. It’s always a good idea to try out different options and see what works best on your body! I encourage you to experiment 🙂

Altering the Center Front Pattern Piece

Since we added length to the side bodice, we also need to add length to the center front piece. To do this, you’ll first need to use a flexible ruler to measure the side front seam lines on both your side front piece and your center front piece.

Note: This is most accurately done by first removing the seam allowance, then measuring this seamline without the seam allowance. I didn’t remove the seam allowance first, because, as we’ve established, I am lazy. When I went to sew up my dress, this meant this seam didn’t quite “walk” – meaning, one piece was slightly longer than the other. I just trimmed after sewing this seam. But if you want to be super accurate, remove the seam allowance at this step, then add it back afterward.

Now, time for more math: We must figure the difference between the length of the altered side front piece and the length of the unaltered center front piece. For me, my side front seamline was 13″, while the center front was 10-7/8″, leaving me to add 2-1/8″.

You’ll add this amount by marking two lines: one at the apex, and one at the lower dart. Then, you’ll need to divide your total difference between these two spots. This shouldn’t be an even split. I added most of my extra – 1-7/8″ – at the apex, and only a little – 1/2″ – at the dart, and I actually ended up removing some at the dart in a later step.

Cut your piece on your two lines. On a scrap piece of paper, draw two parallel lines however many inches apart as you want to lengthen your center front pattern piece at the apex – in my case, 1-7/8″.

Now, align the bottom edge of the top piece of your center front pattern piece against the top line, and the top edge of your middle piece of your center front to against the bottom line. Tape down.

Repeat this with the extra you’re adding at the dart line. Re-draw the seam lines:

Walking the seams

The last thing I like to do is “walk” the seams. Basically, this means holding the two pieces together and pivoting them to make sure that you can line it up at the top, then that the notches match, then that the bottoms match. At this point, I realized I had added about 1/8″ too much at the bottom notch on my center front piece, so I amended that.

Like measuring your seamlines, this step is best done with the seam allowances removed, but it’s not the end of the world if – like me – you’re too lazy to remove them.

A final check

Okay, the real last thing I like to do is tape the pieces together and hold them up to myself. This helps me to see if the curve is reasonable.

It looked pretty good to me, so I went on my merry way sewing!

Sewing the Rosie – General Tips for Big Boobs

And the full bust adjustment for my big boobs worked! I’m loving the vintage vibes of this dress!

My biggest tip for sewing the Rosie is to try on your dress before you insert the lining. I highly recommend this step. You’ll want to do three things when you do this:

(1) Make sure the curve of your princess seams is correct. I had to change the curve of mine just a tad to lower the apex. This is easier to do before you’ve combined your main bodice and lining.

(2) Check the strap attachment points. The strap attachment points marked on the pattern didn’t cover my bra straps, which I didn’t realize until I’d stitched everything together and understitched. Ugh. Double seam ripping! So, try on your dress before attaching the lining and mark where, for your bra, the straps should be. Mine needed moved in about an inch in both the front and back.

(4) Figure out how long your straps should be. Again, I didn’t do this. I just sewed it up as is, not considering that the straps might not be the right length on me. They were 4.5″ too long. When I unpicked to move the straps, I also shortened them.

Another note: I did not use boning. I just skipped this step entirely. While I had boning in my stash, I felt like the boning wasn’t going to be enough to support my large breasts — I’d still need a bra — so I decided to skip this step for ease. This makes the Rosie a comfy, easy-to-wear summer frock!

Greetings my lovelies – Ann here from Designer Stitch. And welcome to my first blog post as part of the Sew Busty Advanced Fitting Series – answering your questions about any fitting dilemmas or problems that you may encounter when sewing all of your fabulous me-made clothing.

Over in my Facebook group I call this – My Teachers Hat 👩‍🎓 – so welcome everyone.

As this is my first post about fitting I am going to talk to you about my FAVOURITE subject – DARTS!!
You may have seen a few previous posts over on my blog discussing darts so you will know that I truly adore them.

Darts are an essential fitting tool that is needed in a sewing pattern. They are key in getting the correct fit of your sewing pattern as they enable the fabric to shape and sculpt itself around your body.

Darts give a fabulous silhouette to the garment to enable you to get the best fit possible.

What do darts do?

Darts are a contouring tool – where a flat length of fabric is shaped to contour around your body.

Darts are essentially a wedge of fabric – shaped liked an extended triangle – that is stitched in your fabric to convert that length of fabric – a 2D shape into a 3D shape.

Where are darts found?

Dart areas can be found throughout the body. Bust darts, waist darts, back shoulder darts, front neckline darts.

Even the shaped side seams of a pattern are essentially darts – except they are split apart to create individual front and back side seams.

Darts don’t always have to remain as darts. Darts can be converted in flare, gather, pleats and tucks.

What happens when there are no darts in play?

The above images are my render of two photographs that were submitted to Sew Busty where the submitter was asking about choosing the appropriate size of the pattern.

Her measures were High Bust = 36″, Full Bust = 38″. And she stated the pattern was drafted for a C Cup. (The body measures as detailed warrant a B Cup). She wondered if she needed a full bust adjustment, due to the wrinkling under the bust.

Regardless of this sizing – if you are trying to drape a flat 2D length of fabric over the body you need some type of contouring device – hence DARTS!!

And you may be saying – Why Darts? The images above indicate that the center front (CF) is lifting and there are drape lines radiating from the side seams to the bust point.

What is happening is that the bust is projecting – dragging the fabric – and then lifting the front hem line to accommodate the projection of the bust mound. (Note: the garment fitted the wearer except the drape lines were very visible. They were drape lines – not drag lines which indicate a garment that is too small).

To offset the front hemline lifting – and the drape lines radiating to the bust point – the length of the front pattern piece needs to be increased.

The above image indicates two lengths of measure – one from shoulder – over bust point – down to hem. The second – from shoulder but straight down without going over bust point.

You can see how much longer the length is that is going over the bust point – than the straight vertical measure.

The above image shows the more the bust projects – the need for a greater length of front pattern piece.

Adding extra vertical length to the front pattern will then allow the sewn piece to contour nicely over the body – but to do this we have to add shaping to that pattern piece to offset the extra length.

And that will be remedied by our friends – DARTS!

OUR FRIENDS – DARTS.

To add extra length to a pattern piece – to facilitate contour – the entire front needs to be lengthened – but as the center front (CF) of the pattern has to be cut on the fold the entire front piece needs to be split and extra length added in.

And so our lovely dart friends come into play xx.

The extra length added to the vertical front of the pattern is taken up with a side bust dart.

The side bust dart is placed at an angle – generally 8-9cms (3 – 3 3/8″) down from your original armhole/scye line – angled to the junction of your front bust depth/bust point separation known as the bust apex (bust point).

Then this dart is usually shortened back around 3 to 3.5cms (1 1/4″ to 1 1/2″) from your bust apex/bust point (but this can be variable)

Adding bust darts to a pattern piece is relatively easy – if you have your correct measures – and of course know how much is needed.

From the original photo that I drew the above images from I calculated that the OP need to split and add approx 2.5cms (1″) to her front length.
