  • Cute top
  • Cute top, well made & color is true to the picture. The bra itself fits well but the stretchy fabric over the bra is too loose. It needed less material & a better tie for around the neck. I am going to try & take it in so it fits better.

Plus Size Underwire Swimsuits

We could all use a little extra support sometimes. That’s where plus size underwire swimsuits come into play. Not only are they super for support, plus size bathing suits with underwire lift and shape, too, meaning these swimsuits actually look more figure-flattering than their stringy counterparts.


There are no style restrictions, either. You can rock a strappy one-piece or a bold bikini and still have the structure you need to look and feel your best for a day at the beach. So pick a color, any color, from understated navy to electric neon, and suit up without fearing a lack of support. With swimwear underwire swimsuits made by your favorite bra brands, your beach body gets the very best.
