Shop for Bra-Sized Swimwear

Shopping for swimwear by bra size has transformed how some women shop for bathing suits. Designed to match your bra size and resemble the fit in one- and two-piece options ranging from A through K, including plus-size swimwear options. Make sure you find a fit with support, coverage, and, most importantly, style! Looking for DD+ swimwear options? Don’t fret! We’ve got an entire selection of DD+ in cup sizes up to L.

Cup-Sized Swimwear Features & Styles

Bra-sized swimwear is available in various one- and two-piece styles that offer a unique fit and feel, including bikini tops, tankinis, triangle cups, balconettes, bandeaus, halters, and full-coverage options. Popular features include wireless and underwire bathing suits in various fits, colors, and designs

Underwire Swimsuit Shaping and Support

Many bra-sized swimsuits have elastic underbands, underwires, darts, and seams for additional shaping and support. Some bra-sized swim tops even have padding in the bottoms of the cups to give you extra lift and shape. Others have light and comfortable padding throughout the cups to give you extra modesty by preventing nipple show-through as well as a shapely, rounded silhouette. Many of our bra-sized swim tops give you the support of an underwire bra and the outstanding fit of a bra-sized cup.

One-Piece Bra-Sized Swimsuits

Purchasing one-piece swimsuits can be challenging, particularly for women with larger bra sizes. Fortunately, bra-sized swimwear is now available up to a K cup, offering flattering fits that enhance your shape, provide ample coverage, prevent spillage, and eliminate the struggle of fitting into a too-small top.

Two-Piece Cup-Sized Swimsuits

Shopping for two-piece swimsuits is more straightforward since they use standard bra sizing. Select a top in your bra size, from B to K cup, and pair it with bottoms matching your style. Most bra-sized swimwear has supportive features such as underwires, contour cups, powernet lining, and seaming. A bra-top bikini is ideal for those who prefer to show more skin. Alternatively, if you want to cover your midsection without wearing a one-piece, a bra-sized tankini offers the flexibility to mix and match tops and bottoms.

FAQs

Which swimsuit is best for a big bust?

For a larger bust, look for bra-sized swimsuits with underwire and adjustable straps. Styles like balconette tops, halters, and full-coverage bikini tops offer great lift and shaping while keeping you secure and comfortable.

How does bra-sized swim differ from standard swimwear?

Bra-sized swimwear uses your actual bra band and cup measurements instead of standard S–XL sizing, ensuring a customized fit and proper support — especially important for those with fuller busts.

Do bra-size bathing suits offer enough support for active swimming?

Yes! Many cup-sized swim pieces are designed with underbands, side support slings, adjustable straps, and seamed cups to provide reliable support for both lounging and active swimming.

Can I mix and match bra-sized swim tops and bottoms?

Absolutely! Most bra-sized bikini and tankini tops are sold as separates, allowing you to choose different sizes for tops and bottoms to get your best fit and preferred style combination.
