Ooops. Ordered this a bit large. It droops on me a bit, and the arm holes are oversized, so they come down nearly to my bra band. It's a basic black dress for summer. Lightweight, loose cut. It's not a low neckline, so if the armholes fit, you can get away with not wearing a tank underneath. I cannot. It's a natural fit waistline. Lots of stretch. I purchased this in XL, my measurements are 36D, 31, 38. It isn't quite as full as the pictures, and the uneven hem isn't quite as defined. It will work well as beachwear for me.
