Summer 2025 is All About the One-Piece—These Are Our 10 Favorites

Innovated fabric made of 100% pre-consumer waste technology creates a super suit for getting your aquatic workout in. The technology also provides a higher shape retention and that's chlorine resistance. The silhouette has full back coverage and is high cut in the chest with an inner shelf liner for bust support to ensure everything stays in place while you're performing breast, butterfly, or side stroke. Another plus, the look doesn’t scream active, you’ll want to wear it while not working out.

This highly rated style from Amazon is made for any active moments in the sun. What makes it particularly great for stand-up paddle boarding are the straps that will stay secure on your body and not distract your rowing. The breathable and lightweight fabric has a four-way stretch allowing for any activity. It also contains UPF50+ for added sun protection while you're standing or kneeling on the board.

Sun, wind, and chilly water protection, this long-sleeve rash guard will help keep any surfer focused on the waves. The sleek design of the zip-front one-piece and ultra-stretchy material allows for full mobility. It's also quick drying, so you can easily remove it at the end of the day. Choose from one of the stunning poppy colors to stand out on the water and sand.

You can trust a bra company that caters to D and above cup sizes to make the best, most ultra-supportive one pieces for large busts. Offered in sizes 30-40 D-J cups, this one-piece suit has hidden underwear and bra clasps. Both provide a secure fit while keeping the look of a pull-on style. Also, there are no hidden cups, allowing for a more natural, rounded shape. Textured fabric adds to the appeal, as do the poppy feminine shades. I recommend red, so you can have your Baywatch moment, but you can never go wrong with pink.

Ruffles, bows, cut-outs, and ties are usually the recommendation for those smaller up top. That is not necessarily a bad thing, but if you are looking for something more minimal, try a wrap front one-piece, like this style from the Gap. A v-neck reads sophisticated and will give the illusion of curves, without adding any volume. You can also customize the wrap front to add a bow or knot and decide how much skin you want to show off.

One-piece bathing suit covers your body a lot more than bikinis, duh! So they make getting an even tan a lot harder. What is awesome about this swimsuit is that not only is it bandeau, but the back is essentially open, other than a bra strap, which you can easily unclasp when laying out. The suit also contains SPF 50, but we still recommend applying sunscreen to your entire body, not just your shoulders, arms, legs, and back while tanning.

Bathing suits can be expensive. Yes, they are worth the money for the most part, lasting several seasons, but sometimes you don't want to spend the money. For when you are keeping your budget in check, check out Cupshe's styles on Amazon. This highly rated style is offered in a range of sizes, has tummy control, is made with good quality fabric, and costs under $40. One of the over 20,000 five-star reviews on Amazon shares that the suit is "sexy, but comfortable. Another five-star comment exclaimed, "This is the most flattering bathing suit." We're sold.
