Beach bikini, sports set for paddle or underwired top for real support: two-piece swimsuits give you more freedom to match the top and bottom to your shape. This selection includes matching sets, to choose from depending on whether you're moving around a lot in the water or mainly enjoying the edge of the lake.

Why choose a bikini?

The bikini is easier to put on and take off, which matters when you're changing by the water. It also allows you to pick a top and bottom in different sizes if your shape requires it. Sports sets stay in place for swimming or paddling, while beach bikinis focus more on looks.

Top, bottom, and support

For a fuller bust, a structured cup or underwired top supports better than a triangle. To move around, a sports bra-style top with wide straps stays in place. For the bottom, a more modest brief holds better in the waves or when getting off a board. Make sure the set doesn’t slide when you raise your arms.

Other women's swimwear pieces

To mix and match freely, check out the tops and swim bottoms sold separately. For swimming in a pool, one-piece swimsuits are more practical. Swim shorts complete the outfit for paddle boarding, and the women's swimwear page shows the full range.

Bikini brands

Arena offers sets designed for swimming. Fantasie features structured underwired tops for genuine support, and Elomi and Freya provide other matching styles. Billabong and Protest bring in bikinis with a surf and beach vibe.

Good deals on bikinis

Between seasons, some sets go into the swim sales. Also, check the new arrivals to see the latest prints.

A set for every activity

For swimming at the lake after a hike, a lightweight bikini dries quickly and can fit into a pocket. For paddle boarding or kayaking, a more covering set with a sports bra avoids readjusting with every move. For a family beach day, a more structured top and high-waisted brief provide confidence when playing in the waves. If you’re doing laps, opt for a sporty bikini rather than a tie model, which might slip in the water.

Also think about the sun: a covering top or a long-sleeved model protects your shoulders during long sessions out on the water. And if you’re torn between two styles, a neutral top easily pairs with various bottoms to mix up outfits during a getaway.

Frequently asked questions

Does a bikini stay in place for swimming?

Yes, if you choose a sports set with a covering top and wide straps. Tie bikinis are better suited for gentle swimming.

How do I choose a top that provides good support?

Look for a structured underwired top, shaped like a bra. It distributes weight better than a triangle model.

Can I get a different size for the top and bottom?

Yes, that’s the advantage of tops and bottoms sold separately: you can adjust each piece to your shape.

What bikini is best for paddle boarding?

A sports bra that provides good coverage and a bottom that stays in place when you get on the board. A swim short over the top also protects from the sun.

How can I prevent colours from fading?

Rinse the set in cold water after each swim and let it dry in the shade. Direct sunlight and chlorine fade fabrics faster.
