I'm 5'3 and 137 lbs, ordered a small and they probably fit like a medium, just have too much stretch in them making them larger than they should be. It's not slimming as stated in the description so the fit was loose around my legs and ankles which wasn't what I was expecting and not my style at all. They are soft and felt comfortable to wear but just weren't the type of leggings for me after trying them on and I knew I wasn't going to wear them so I returned them.
