The name alone should give much warning about how to order ladies. This material is TIGHT!!!! I ordered a medium and a large and can't fit either one. The large I can get into it's just so tight you feel trapped. The medium is a lost cause. I'm 5'11", 157lbs, I'm not curvy like these models nor do I have a big butt. If that info is of any assistance for the next woman trying to order.
