I bought this in size 18. This is a great suit and nice quality, far above the clearance bargain price. The cup sizes do run small, the sizing chart says this size is a D cup, but i wear C and this fits me perfectly. I carry my weight mostly in the belly area, and out of 5 suits i tried, this is the most flattering. the lines and black area cleverly make you appear a bit slimmer. I was looking for a suit that revealed as much skin as possible for a sexy, sunny look yet hid the jiggly bits as well as possible. this works quite well.
