ok this is NOT A CORSET this is a "corseted" top its just for looks not shaping or any of that(duh), its also short it  dosent reach my hips at all the sizing is indeed a bit off but not much(so long as you have a short torso) i wear a 14 so the XXL fits fine fully closed and mine came with a thong.....for 30 some bucks im not going to complain
