Love these leggings, but they run small.
I'm 5'5" and 110 lbs. I have a very petite frame with 34-inch hips, and these leggings are quite tight on me. It's hard to get them on and take them off. They look fine, but I find it hard to believe that the model in the photo, with her curvy frame, is wearing a size XS. If I was to order again, I would probably try a size small. I am usually a size 0 or 2 in pants and again, I'm very tiny, so if these are tight on me, they will probably be tight on you.
