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, the lace’s shoulders are cute and not that long, so it won’t feel itchy�� 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)
