My measurements don't fit the usual for women, so I have to modify
patterns or make my own.

You are almost exactly Connie Crawford's size 2x -- you'll need to reshape
the side seams in the waist area to account for your straighter waist.
Easiest way to get a pattern to try is probably through the series she's been
doing for Butterick.

There are more on her own website: http://www.fashionpatterns.com
I'm not sure why Butterick is using just the sketches on the website -- if
you look in the paper catalog, you can see samples that are actually on models,
and it's easier to visualize the garments for a lot of people.

I believe her plus sample size is a 3x D, about 5'4" tall. That means you're
not going to see the giant shoulders and neckline and other infelicities
induced by grading up a 2x from a 10 with the usual rules. She makes her
patterns twice, once for misses size and once for plus because the proportions
change between those two ranges. Most are fairly basic because she wants
people to be able to


My mom was about your size and the 2x patterns fit her almost out of the
envelope (I had to do some altering for a shoulder issue) Made it very
easy for me to keep her in clothes. I did not have nearly the luck with
most other patterns, other than the ones I drafted especially for her.
