Pants fitting, part 1

First, I'd like to thank all who commented on the fitting issues for my pants. I did look at Debbie's site and somehow thought it would not be the "one" answer to my problem, as I've become convinced that there is no one-step solution for me. But I think I have found part of the solution there. Tonight I spent adapting my pattern and making a muslin.

My starting point, after reading all the information was the Threads issue of January 2006, an article by Joyce Murphy Adjusting pants from waist to seat. In this article she describes "body space" as an important point in fitting pants. And it does make sense to me, as women have very different shapes. One needs more space in the front, and others (like me) more in the back.
The picture above shows the body space in my pattern, which is 15 cm. I tried to measure my own bodyspace by taking two rulers, and it is 19 cm, which means that 2 cm more is needed (half of the extra width in the pattern). The article describes how this must be done after pin-fitting the muslin, but as I have no one to help me with that, I tried to do it in this more theoretical way, by measuring.

In this picture I tried to show how I measured this (alone in the house, so no one to take a better picture). Standing with by back to a wall, one ruler to the wall, and the other over my front, meeting in a 90 degree angle. My ruler has white space to start with, so the actual size is 19 cm.

The adjustment that follows from the article can also be seen in the first picture. The 2 cm is taken from center back, and added to the side seams.

After this adaption I made my muslin, and this was the first result.

Not too bad, the diagonal wrinkles are gone. The white is waistband interfacing, that I added to get a good impression of the fit with waistband.

This is the result of stitching the crotch a bit deeper. Not a great improvement.

And this is the result after pinning extra width away. (Did you ever try to pin pants you are wearing on the back? Not a great experiment!)

This is where I stopped tonight. This looks much better, and I think I now need the fish-eye adaption on Debbie's site. But that is for Friday.


  1. Much better! I have to use a "fish eye" dart on the back of my trousers from Marfy and Patrones, too. I use Debbie's method and have had great results.

  2. I think you may have solved your problem. This looks much better. Make sure you can squat in them--that's my little test for enough leg width and crotch length. Good luck!

  3. Wow! The change is incredible. Congratulations, fitting pants is so difficult.

  4. You are doing a great job, Sigrid! The pants look much better! Thanks for sharing this process with us, I find the subject of fitting pants one of the most defying and I'm sure this information will help many others!

  5. I just wanted to stop by and thank you for this post. I was altering a pair of trouser and was having trouble with the fit in the seat. A quick google search led me to your blog and voila! My problem was solved. Thank you so much for the post and pics.

How to sew a sleeveless top with facings

How lovely to read the nice comments on my jacket. Grumpy without coffee commented that the original artist for the cartoon (which apparently was for books) was Sarah Andersen. Thank you for mentioning it. Beckster asked about the way I closed the center back seam of the lining. I did it by machine. She also said “Although I have not tried it, I have been told that the lining can be made by using the pattern minus the seam allowance and facings.” Well, certainly not without seam allowances, it should be without hem and without the facings. Important is that you have about 5 cm hem in the jacket for this to work. And I would always make a center back pleat. It gives you space to move without the lining pulling on the fabric. Next time I make a jacket I will try to make photos of the process of bagging the lining (Patsijean said she would have liked to see them and probably more would be interested). Might take a while though, see the end of this post.-----------------------------I mad…

Dress Burda June 2018, construction picture

Once in a while a pattern shows up in a magazine that I want to make immediately. This Burda dress from the June issue is one of those.

It’s mainly the linedrawing that’s interesting, as the fabric they used for the magazine issue is not really showing the design lines. There would have been better accent options for the piping they uses.
If you’re like me and in general don’t look at the Burda instructions but do it by experience or your way anyhow, DON’T go on autopilot with this one.
Sleeveless dress: I close shoulder seams at the last possible moment. Not here, as you have to sew the bias band in between the center and side parts. The band has no seam (and I wouldn’t add one, too many layers of fabric), so the shoulder has to be sewn earlier than I’m used to.
Darts: I was inclined to sew all darts as first step and realised really just in time that the front dart is taking up the edge of the band. Front and back band! I was stupified why the angle of the band was not matching th…

Hilarious description

This week I bought the January Burda issue and browsing through it this top, and especially its description had my attention. Written by someone who has no understanding of modern, functional fabrics and never goes to the gym. Don’t know whether it’s the same in the English issue of the magazine, but in Dutch it says “Sport shirts often have the disadvantage to be close fitted.  This restricts your movement. Our suggestion: make this shirt with a full draped back.“I didn’t care to check their description of sports shirts they published before, but thought this one was hilarious.Off to trace a pattern from this magazine (not this one).
