I normally wear a medium so I ordered these in a medium. I wasn't even able to get them past my calf, the ankle has no give or stretch. I ordered a large for my daughter, which she couldn't get past her knees, the waist is not stretchy. I tried on her large and that didn't fit either. I don't know what fabric they used but these are my worst pair of Fabletics. I don't think I would order another pair because of the lack of stretch. Now I'm stuck with 2 pairs of tights that don't fit and don't fit anyone I know.
