Don't judge this picture, its for sewey people who care about back fit, so the poofing at the center top is probably my fault, I added a wedge up there for a small fuller seat adjustment and will have to shave some off next time. Heres a picture illustrating what I did to the pattern. My pointer finger is pointing to the wedge:
I also lowered the lower crotch curve a bit and cut at the size 14 for the pointy bit of the crotch above the inseam. This was all in an effort to accommodate my tush. Worked pretty well. These shorts don't have the most flattering back view but meh, can't win them all and they were a relatively quick make.
Thanks for reading and happy sewing!
