This must run in childrens sizes. For reference I am 54, 160lbs & a size 6 in jeans. After looking at the reviews I ordered way above my size. According to the size chart I should be a size XL, I ordered a 3XL it was still too small. It was so tight I could barely get it on. Once I did, the material was cutting into my thighs so bad it hurt. Will be returning.
