12 Athletic Swimsuits For Large Busts

Adidas Iconisea Swimsuit ($54, originally $90)

This swimsuit goes from size 1X to 4X, and offers maximum support for super-active days. The brand calls it the little black dress of swimsuits, because of its classic shape and smart design: thick straps for comfort, a U back for style, and sewn-in pads that won't slip around when you wash it. It's a suit you can slip on and forget you're wearing, which is the best kind of suit.
