I'm 5'7" 208lbs, I ordered a size L but unfortunately, it was a little tight for me. Even so, I would like to commend the material and cut of this dress, Its material is very comfortable to the touch and close to the skin, not particularly thin, which makes it impervious to view. I think I'm going to contact the seller to get an XL size, it will be the length I want (2" from my knee)
