The most comfortable swim tops and one-pieces—for real support across cup sizes.
The most comfortable bathing suits are the ones that combine high support with subtle details and are meticulously constructed to fit just right. Bust support matters for every cup size, from A to D and beyond—and supportive swim bottoms matter too. We also believe supportive swim should be easy to find. So we edited together our most supportive swimwear, from high support one-pieces to the bikini tops with ultra-supportive details that make all the difference, and the bottoms that pair with them best.
Our styles offer sustainable swim with straps that don’t stretch out or weaken—these provide uplift and support while holding your boobs in place. The thickness and strength of the straps matter; ours are meticulously designed to combine ultra subtle support without compromising style. Next are our underwire bikini tops: these supportive swimwear pieces combine molded construction with the structure and strength of underwire to help shape and support. We also design with intentional accents in the right places like our ring-adorned Skylar top, for the ultimate combination of form and function… beach days just got easier, sexier and more comfortable. Below, find our bestselling, essential swim silhouettes—with support.
