I ordered a small. It fits well. There’s no compression. I do not have a large butt, and my cheeks still didn’t fit into the mesh lol. Just made it look odd. There’s no pee hope. The thighs, were the lace is attached, is tight. Just pull it and it will loosen. I am 140lbs, 5’2.
Fits great I have lots of extra room for post op swelling. Worth the price and very quick shipping.
