First off--what's a tankini? And why should you buy one?

A tankini is a two-piece swimsuit--it gives you the flexible sizing of a bikini, but with a longer top that provides more tummy coverage. A tankini most often is a swim top that fits like a tank top that we pair with bikini or swim short bottoms, but you can mix and match to get your perfect suit. Size small on the bottom but DD-cup on top? Choose a supportive, underwire racerback tankini top (check out our Metis Underwire Tankini Top ) and pair it with our boyshort bottoms. Want athletic swimwear but can't deal with the restrictive feel of a one-piece? Get a form-fitting tankini top and pair it with stay-put bikini bottoms .

How are tankini swimsuits sized?

Swimwear made to move has to fit just right--and we know that small, medium, and large don't cover all the shapes and sizes women come in. That's why many of our tankini tops come with band and cup sizing (here's looking at you, D-cup and up) and adjustable straps. Mix and match a bra-sized crossback tankini top with your favorite swimsuit bottom to get just the right swimsuit combo for your body.

How should a tankini top fit?

A tankini top should have all the same features as a well-fitting one-piece or bikini top. Look for a snug fit (swimsuits stretch a bit when wet) that doesn't gap or pinch. Check out our How to Choose a Swimsuit guide to get the lowdown on swim sizing.

How do you keep a tankini top from floating up?

The key to a top that stays put? It's all about fit. While blouson or flowy style tankini tops tend to billow a bit underwater, snug-fitting tankini tops or tankini tops with drawstring or elastic around the bottom hem stay put while we're active, whether we're going for a swim or playing with the kids. As long as you have a great fit, you can choose the top style you feel the most comfortable in, from twist front to v-neck to bandeau.
