Sexy White and Black Cocktail Dress

This is a nice dress I got as a gift. However, it's a small (I would imagine dress size 2 or 4) and I'm a medium (size 6). I've worn it once in public (and another time to take the photos above). In case you are wondering my (girl in photo) measurements are 37/26/38 with an inseam of 33 inches, so compare that to your own.
