They fit like slim clothing so if you’re not slim in the waist/legs then order a size up
This pair is my favorite of the two I purchased. I love the simple design. They're a perfect thickness, super soft inside and can fit as low or high waisted for women. They do fit a little tighter in the butt area since they're made for men, but it isn't enough to affect comfort or how they look. (I'm 5'4", 130lbs, 36-26-37) My 13yo son keeps stealing them and wearing them too - I think I'm going to have to get a couple more pairs so he can have some of his own!
