I hate, hate, HATE buying women's pants. I never know my size, and they all have such a small crotch/thigh space. Even if I buy my size, it's like the pockets are painted on. I can't shove a phone and a wallet in them!
And don't get me started on skinny jeans!

I have muscular legs, and they like to have room to move! Also, since busting my foot a few years ago, my right ankle doesn't have the range of movement it use to have, so pointing my toes to navigate a skinny pant leg gets problematic.
...Though, I do have a pair of men's super-skinny jeans that fit absolutely perfectly and better than the skinny jeans. Whatever.
