So this dress is super adorable. The back is smocked but since material is like a silky/cotton feel is has minimal stretch. The breast area is pretty narrow so a bra shows. No bra = no support. It is very short, just like on the photo SHOOOORRT. For reference Im 5'1, 145 lbs 38D (38-28-43) and bought a Small. The medium would have been too big on the waist. I might return it just because of the length.

Don’t get me wrong, the dress is beautiful and it looked beautiful on me. I ordered a M and it fit like a glove. But the material is very thin and the dress is shorter in person.
