Customer Review: “An exception to ‘bikini tops never fit me right.’ With small boobs and wide ribs, I hardly bother with two-piece suits because they’re often not so flattering. This one looks great, fits great, comfortable enough to sleep in, and I actually have cleavage (one star deducted only for seams and pads that wouldn’t lie flat at first, but probably will with use).”

Cons
- Pull-on style
