The movement toward bra-size swimwear is a welcome development since it allows women to get a much more accurate fit in both the cup and the band sizes than previously. In addition, an underwire gives firm support to full-busted and plus size women, lifting and rounding the bust. Styles include contour cups with light padding for modesty and no "show through," and multi-part, seamed styles that help shape the fuller bust. Many of the better swimwear manufacturers have gone to bra-size bikini and tankini swim tops, as well as one-piece swimsuits. We think you'll be very pleased with the wide diversity of looks as well as the excellent fit.
