I just bought a pair of these pants, in my size and there a bit snug, anyone known if they stretch? I feel like if I go up to the large, they'll be. Anit loose and I don't really want too loose, like jeans. They don't feel terrible, my ass looks great. Lol, but they are just a HAIR snug. I feel like if they stretch just a little, they'll be perfect, but I don't know if these pants stretch or not. Hate to send them back and wait again, only to find the large are just a little too loose.
