Can I fix the rise on these trousers?
I just recently picked up these trousers (pinstripe) from the women's section and they fit great apart from the crotch area. I need some more space there and I did some research and think it's the rise that's too short (feel free to correct if wrong). I compared them to another pair of trousers that I like and got the differences (as seen in the images). I saw some people saying that adding a gusset could increase the crotch area but I'm not sure how much to add or if I can even add enough to fix the problem.
I'd appreciate any insight that you guys could provide on how I could potentially fix it, thanks in advance.
