This dress has some sort of boob magic. It seriously rocks! The material is nice and thick so its not see through and it feels well made, because its thick you shouldnt need to wear a bra if you're worried about seeing your nipples through it. Its long enough that it covers my butt (I have a big butt) and short enough to stay sexy. The straps also come off so you can make them criss cross in the back, normal or strapless which is cool. I am 57, 200 lbs, 43 chest, 38 waist and a large B/ small C cup breast size. I ordered an XL based on the measurements and it fits perfectly.
