Making pants for Frances that fit is one of the reasons I got into sewing clothes.
It’s also one of the most challenging projects I’ve ever worked on.
I’ve tried so many patterns and so many alterations, and most of them, Frances couldn’t wear. They were too tight here or too loose there or too low-cut or fit on the legs weird. So in the meantime we bought a lot of very loose blue jeans in bigger sizes and hemmed them shorter.

Frances’s body grows differently; it’s part of her genetic condition. Her bones are a lot shorter, the joints are a slightly different shape, her back is quite curved, her ribs (and therefore torso) are bigger. Relative to other kids her age, she needs pants with a bigger waist, a snugger back, shorter legs; and then of course she likes things to be in her own style, which at this point in her life means “casual.”
It’s been an incredibly long project to get a set of alterations that fit her well and she enjoys wearing. But by George, we’ve finally done it.
Theses are the first pair of proper blue jeans I’ve made for her that she actually wears, and that fit.
They are not perfect. My sewing machine was incredibly unhappy about sewing through all the layers of denim and interfacing on the waistband and at the seams, so the topstitching is crap. One of the belt loops was sewed on a bit crooked.
Otherwise. I LOVE THESE. And so does Frances.
The pattern is a custom hodge-podge of Jalie stretch jeans, an Ottobre denim shorts pattern, and a trace-off of Frances’s favourite Old Navy Jeans, all with her alterations. The denim is very heavy, 97% cotton 3% spandex, from European textiles on Ottawa St N in Hamilton. $9/m, I think, so they were overall cheaper than Old Navy jeans. Nice metal jeans zipper. The pockets are quilting cotton with an adorable fox pattern on them, because Frances loves foxes.
I rigged up a buttonhole-and-button setup on the inner back waistband so we could get some buttonhole elastic and ensure that the back waistband is as snug as she wants it to be. It’s not as tidy as I would have liked, but it is functional.
My sewing machine went on strike over the buttonhole at the front: too many layers of fabric. I tried four buttonholes and ripped out three; the last one only completed halfway. So half of the buttonhole is by machine and the other half is by hand. It turned out pretty neatly, I think.
They fit her well (YAY!) but I have a list of small tweaks for the next one:
- take some length and depth out of the front crotch curve
- angle in the back yoke a bit more to make the waist a bit snugger back there.
- add maybe half an inch to the back rise
- lower the front pocket curve by about 3/8″
- deepen the front pockets by an inch
- and use angled pockets for the back rather than the rounded ones that came with the Ottobre pattern.
I can’t emphasize this enough, Dear Readers: rounded back patch pockets in thick fabric with contrast topstitcing are the devil. The fabric doesn’t want to fold in nicely to match the curve, even with gathering stitches to help; and the sewing machine has no interest in moving smoothly around that curve while topstitching afterwards. Angled pockets. They’re the way to go.

The important thing is that now we are a hair’s breadth from having a perfect pants block for Frances. So I can make her pants that she can wear, hallelujah.
Also hallelujah: Frances has decided that the next pair of pants she wants, is leggings. That should be a much faster and easier project than blue jeans, even having to trace and alter a new pattern. (And in fact they’re already done, traced out and sewn up in a single day. Thank goodness.)
But after that: more jeans. More leggings. Fancy pants to wear when she needs to dress up and doesn’t want to wear a dress. Pants forever.
I cannot wait to make All The Pants for Frances. Frances now has a lifetime Pants Avalanche coming her way.
These are great! So happy you found a good pattern for Frances. I’m on the quest to create good work trousers for my husband. I am sure I will have the same feeling of relief when it works for him, too! 😀
Found–or made. 😉 But at least now I have one and can use it as the basis for other patterns.
I saw that! I’m sure you’ll do great. BTW, I find that plastic zippers are fine so long as the fabric is light- to mid-weight. It wouldn’t work for a heavy denim like these ones, but I regularly use plastic zippers for work pants and if anything, it’s better because you can shorten them if you can’t find the length you need.
Ooh thanks for that. I’ll use the plastic zipper. It’s the right size so buying a bunch of new ones made no sense when I had over 20 left! I meant to write made. Lol.
