I am a franken-patterner! I will follow the bodice directions but I almost always ‘create’ the skirt part of a dress. You may have noticed my vintagey style. I haven’t been keen to rock wiggle skirts/dresses after I took an Internet tongue lashing about my body shape when I posted this über fitted skirt. So floaty, 50’s inspired skirts it is!
[break]
Many of the circle skirts available in the shops are actually half circle. Half circle is still pretty floaty and very poofy with a petticoat. I think half circle is more flattering for a large stomach area and it’s less fabric intensive. Fabric for a full circle skirt is out of control for me because of my large waist measurement and desire to have skirts knee lengthy and not panty grazing! My size will fit, in one piece with only a centre back seam, on fabric only 1m wide! I have to fold it lengthwise but it can be done.

So how do draft a half circle skirt to fit an existing bodice pattern?
[break]
I am very, very easily confused by the math in sewing. This means I’ll minimize it where I can. So in this set of calculations I’m assuming you’ve sewn up the bodice, leaving it open at centre back, where the zipper will go. If you can measure the pattern pieces and calculate how long the resulting bodice will be after seam allowances and darts, more power to you!
So, the blue lines indicate where I have seam allowance. I want them to be part of my skirt too. That way the bodice and skirt will line up and I’ll have space for my zipper etc. You need to measure along the whole bottom bodice, as indicated by the red line.Measure the bottom of the bodice, including the seam allowances at centre back. Let’s call that measurement (A).
(A) divide by 6.28 = (B)
(B) X 2 = C is your final measurement for your waist, write it down!
[break]
Real life example: (A) for my bodice is 41″ so my calculation looks like this…..
41″ divide by 6.28 = 6.5″
6.5″ X 2 = 13″ this is my C
[break]
Measure from where the bottom edge of the bodice hits you, to where you want the skirt to hit (I). Then note the seam allowance specified for sewing the skirt to the bodice (J). Decide on your method of hemming and therefore how much you need for hem allowance (K).
(I)+(J)+(k)=(L) is your final length measurement, write it down!
[break]
Real life example: I want my skirt is 24″ long, have 1/2″ SA but I only want to add a 1/4″ hem allowance as I will be using bias tape to hem it.
24″ + 1/2″ + 1/4″ = 24 3/4″
[break]
Armed with a ruler, tape measure, marking device and big bit of paper/pattern trace/whatever you draft on – we pattern make!
Start by marking a straight line across the top (horizontally) and a straight line down the side (vertically). Make sure they meet at a perfect 45 degree angle! Mark your C measurement on each line, working out from the corner (yellow). From the end of your C line, measure down the lines the distance of your L measurement (red). At this point, you’ll only have the red and yellow lines marked. You’ll need to use your C measurement and a measuring tape to mark dashes, as per the next pic.
You’ll need to join these up to make a quarter circle shape. If you are like me and want to be sure you did the math correctly, the curved line should measure half of your A. This makes your waistline. Then add your C and L measurements together. Pivot the sum of them from the same corner to create your hem line. Just the same way you did the waistline. Cut your pattern out. Place one straight line on the fold and you’re done!
[break]
The same theories apply to skirts with a side zipper. Just measure the bottom of your front and back bodice pieces and add together, before you sew the side seams – that will be your (A). And cut two skirt pieces, rather than cutting on the fold.
I hope this helps you to franken-pattern to your hearts content! I used to be frightened of matching half circle skirts to bodices and now I’m free to make twirly but slimming skirts for any bodice I like! My most fave half circle skirt is part of the Tiramisu dress from Cake patterns, that’s what you see in the pic above. I will have a franken-pattern dress to show you that uses this technique but I’m still doing the hand sewing, so you’ll have to wait! If you are feeling full circle, I have a reversible, no hem version for you.
EDIT: I have finished sewing this Simplicity 4070 bodice with a self drafted half circle skirt. For more details on the dress and a tutorial on how to add the décolleté collar, check out this post xxx

This is really cute and the color is great. I’m on it cause I want one too.
I am very, very late to the party here (I just found your blog today having started to sew recently), but I had to say something, even if it never gets read. I actually think you rocked that fitted skirt. Anyone who feels the need to publicly comment and tear down a woman over her body/choice of skirt is a sad, pathetic individual. They deserve our sympathy but not our time and nor should we take what they say to heart. That skirt looked fantastic on you and I think you should wear whatever you want, and not pander to the keyboard warriors out there who have nothing better to do than be mean to people they don’t even know.
So yeah, keep doing you and forget the trolls. Have a wonderful day! xo
Never too late! And your comments are so heartening.I fully embrace my body and sew to fit it. Internet meanies have no power over me! That said, I so appreciate your kind words! If you are new to sewing, there are so many tutorials here that keep things easy. So take a look around and enjoy your sewing xxxx
Thank you for this great tutorial. And I agree with Ricci ~ you look wonderful with that fitted skirt! Ignore the sad trolls and be your colorful, creative, beautiful self.
Oh thank you! I have actually been wearing another version of the fitted skirt recently and I’m very happy! And I should have a how to sew stripes into half or full circle skirt post up soon….so stay tuned!

Thank you for this! This is EXACTLY what I needed!
My pleasure! Happy Sewing xx
Hi Sarah! I’m just starting sewing, so far I’ve managed to sew boxer shorts that are far too large and a tutu that also doesn’t fit. Lol.
This is such a great tute – thanks heaps for sharing your knowledge and enthusiasm! I also just want to note that you rocked the lovely green skirt. Screw the haters, wear it anyway. I’ve been body shamed for being too thin and too thick – can’t win why bother?
I’m going to try and make my own franken-dress now, fingers crossed I keep my stitches straight 😂😂
Keep at it! Sewing can be tough in the beginning but persistence pays off. I’m sure you franken dress will be lovely – send me pics! And since the green skirt episode, I pulled out an unfinished muslin of it and have been wearing it proudly (see here).
Good luck with the sewing! I’m always happy to help if you get stuck xx
Love the tutorial! Frankenpatterning is a great way for people to get just the right dress pattern for their own tastes! One thing that confused me about the actual patternmaking part, though: a vertical and horizontal line won’t intersect at a 45 degree angle. Did you mean a 90 degree angle, or am I reading something wrong?
Hi! So the pattern is only half of the skirt. You can either cut it with one edge on the fold and have a single back seam or cut two pieces and have two side seams, it depends on works for what you are making. I suggest you check out my half circle skirt tutorial too, it might make things clearer.
If you get stuck, flick me an email. S xx
Hi Sarah! I love your tutorial and I will try to draft my pattern based on this advice, but I have one question:
As I am gonna sew a floor length skirt, I need more fabric than the width is. Do I need to follow the grainline and join two pieces together or could I lay my pattern accross the grain?
Hi! You can lay it on the crossgrain no worries. The nature of any kind of circle skirt means parts of the hem will be on the crossgrain, straight of grain and all kinds of bias anyway.
Depending on your size, panels maybe useful. I have a post on how to work with panels, if you need it.

Help! I need to pattern make a gathered circular skirt for a Wedding gown. The bodice is shaped to below the bottom In centre back then sloped up to a peak in the centre front approx 10cm from the waist. I am planning 5 half circles meaning the centre front shaping is causing a headache. Of course I want to have the same half circle which falls correctly. I know how to do the pattern for the slanted pieces but the centre peak is the issue.
Do you know how to do that or could you advise me of another source? Thank you June
Hi,
I am sorry but I’m probably not the best person to help on something fancy like that. You could try the forums at Burda, Craftsy, Pattern Review or even Reddit. I have been watching Angela Clayton lately and she might be a better bet!
Sorry I couldn’t help. Good luck & happy sewing xx
Thank you anyway Sarah. I did not know where to find out. However eventually I figured it out after deliberating for quite some time and a couple of trials. All good now and keep up the good work as I see you are helping lots of people. Thank you for replying promptly. X June
Lovely of you to say that you enjoy my work! Trial and error is often the best way. Many of my tutorials come from me not being able to find the information, messing around till I get it and sharing the results! I’m sure you project will turn out perfectly xxx
Another late comer to the party! Thank you for this tutorial – now I’m off to to hack some new dresses!
I was really sad to read your comments about not feeling confident about wearing fitted garments. I looked at the skirt in question and, girl, you rocked it! You have a fab sense of style and I think I’ll be stealing ideas from your posts for me and my friends.
Never too late to this party! I am so glad this post still helps people make swingy dresses. I’d love to see you hacks, please tag me in pics or email them over.
Thank you for the body positivity! I’m over my tight skirt fears and rock by big ole belly line with pride. Life is too short to feel bad about internet meanies!
Happy sewing xxx
So I too am super late to this party, but I just had to say something! I LOVED you in the green wiggle skirt! It was so nicely taylored and it was totally sexy and elegant at the same time! You rocked it. Don’t listen to the trolls, don’t even give them the time of day. They’re disgusting and should learn the golden rule. We should all wear what we love not what other think is flattering. But on a side note it was flattering anyway, but that is not important, what is important is that you loved it! Its too bad keyboards don’t shock people when they write something mean spirited! ha ha ha ha
