I bought these in black in Christmas and the size I got was medium, they were super big and gathered a lot on the legs and ankles….so I gave them to a friend who filled them out beautifully. Even though I had only worn them once, I was so in love with how they fit, how they felt, the smoothness and just how comfortable they were, I went and bought another black (extra small) and a stone (small)….they didn’t have small in the black so that’s why I got extra small and I was a bit hesitant they would fit but they did and they actually are still a little big on the legs and ankles but not as bad as the medium. I love these leggings and I would wear them daily!
