The Best Bra-Sized Swimwear & Swim Bras

Bra-sized swimwear is perfect for summer because it combines the support of an underwire bra with the outstanding fit of swimwear cups. Whether you're heading off on a beach vacation or doing laps in the pool, Bare Necessities has a vast selection of bathing suits by bra size in a rainbow of colors and styles tailor-made for you and your warm-weather plans.

Bra-Sized Swimsuits by Cup Size

Bare Necessities applies the same expert bra sizing to both lingerie and swimwear, which means you can get that same perfect fit you know and love in a supportive swimsuit in your cup size.

The best way to determine your bra size is to measure around your ribcage just below your bust to get the band size, then measure across your boobs to get your bust measurement. Put those measurements into our calculator and we’ll tell you what your bra size is.

Once you’ve determined your bra size, you can apply that to tons of different bra-size bathing suit styles, from bra-sized bikini tops to bra-size tankinis and even bra-sized one-piece swimsuits. Now, you can focus more on having fun in the sun, and less on whether your suit is supporting you enough. Your swimsuit cup size is typically the same as your bra size, which makes swimsuit shopping for the best bra-sized swimwear easy.

What Swimsuit is Best for Big Breasts?

Supportive swimsuits that offer the same structure and comfort as your favorite bra are typically the best for women with big breasts. This means that the swimsuit has a built-in bra  for DD-plus busts (including H-cup sizes) and underwire to keep you feeling confident in the water and on the beach.

Some people might think that having a larger bust limits your swimwear options, but that’s simply not true. Built-in swim bras come in all different styles, colors and trends. From a tankini top to a bikini top to a one-piece suit, there’s no reason to limit yourself.

Frequently Asked Questions

What is bra-sized swimwear, and why does it fit better for a fuller bust?

Bra-sized swimwear is sized by band and cup, like a bra, instead of small, medium and large. That gives you a more precise, supportive fit, with built-in bra construction and underwire in many styles. Our Bra Fit Experts apply the same sizing to swimwear as to lingerie, and your swimsuit cup size is typically the same as your bra size.

Which swimsuit styles offer the most bust support and lift?

Look for styles with a built-in bra and underwire. They come as tankinis, bikini tops, halters and one-piece suits, so you can choose the cut you like without giving up support. For fuller busts, including DD and larger and H cups, a built-in bra with underwire gives the most structure in the water and on the beach.

Who makes bra-sized swimsuits?

We carry bra-sized swimwear from brands including Freya, Elomi, Fantasie and Panache, in a wide range of colors, prints and cuts.
