What We Love: Made from recycled plastic bottles, the fabric is buttery soft yet supportive.

What We Don't Love: The suit can run a bit short so size up or go with the long fit.

Londre founders Hannah Todd and Ainsley Rose started Londre to create swimwear that's sustainable yet stylish, and their first design is the brand's best selling style today. This one piece is sneakily sexy, with a scoop neck, low back, and a cheeky butt that won't sag thanks to the scrunch design. Made from recycled plastic bottles in Vancouver, the fabric is compressive and molds to your body overtime. "I've tried the brand's bikinis and I love how silky and sturdy the material feels," says Emily Cieslak, assistant commerce editor. "The colors are really beautiful too." Because it can be hard to find your size in one piece, this style comes in both a classic and long fit to better fit those who are above 5'7" or have a long torso. And if you would like to shop around, senior fashion commerce editor Chloe Anello owns and loves this option from the brand, for a more feminine silhouette.

From all the one pieces on Amazon, this design stood out to our ecommerce writer Christina Butan due to its casually sexy design.

"I was pretty shocked by not only how comfortable the Viottiset swimsuit was when I slipped it on, but how flattering it looked, too," says Butan. "It doesn't feel suffocating or squeeze me in the wrong places, and the cheeky cut is just cheeky enough that it's super cute and won't get scrunched up in your derrière."

Also available at Cupshe and Target

What We Like: The scallops and cutouts make this suit extra flirty.

What We Don't Like: You may get some underboob action.

Scallops add a little pizazz to the most basic swimsuit, and this design by Cupshe is the perfect balance between simple and flirty. The knotted top is extra adorable but also provides the functionality of adjustable straps, removable pads, and a back hook closure. Those with bigger breasts may have some underboob, but as celebrities like Kendall Jenner demonstrate, that's not necessarily a bad thing. The silhouette isn't too high cut for those that want more coverage and the scallops soften the lines so your legs never look cut off.

What to Look for in a One-Piece Swimsuit

Materials

Sometimes, your swim plans only consist of lying by the pool or on the beach. In those cases, you can't go wrong with most swim fabrics. However, if you plan to swim regularly in chlorine or salt water, look for durable fabrics that have been proofed for chlorine and offer sun protection. These features, along with proper care, can help your swimsuit last longer.Today, you can also find swimwear with compression material that provides extra support to areas like your tummy and butt.

Padding

To pad or not to pad? Many swimsuits offer removable cups while others come with no padding whatsoever. Depending on your cup size, you may appreciate the extra shape and support of a built in bra as well as the nipple coverage. Othersmay enjoy the more natural look and feel of no padding. "Swim padding is always a personal choice. Some people, myself included, don't care as much and love a little side or underboob," says Rosenbaum. "Others want their ladies locked in place. If you're the latter, I would recommend a suit that at least has optional removable cups."

Lining

Have you ever come out of the water only to find that your suit has become practically see-through, especially in all the wrong places? That's the pitfall of unlined suits, even if the fabric comes in a dark color. To avoid the mishap, double check if the suit is double lined, especially when browsing cheaper styles. Also note that some suits have a light inner lining, even when the outside shade is darker. The lining can pop out as you swim and move around, so if you think this mismatch will bother you, look for suits that are the same color on the inside and outside.

Your Questions, Answered

How do I shop for a one-piece when I'm different sizes on top and bottom?

One of the downsides of a one-piece is that you can't choose a different size top and bottom, as you can with a two-piece. Don't give up though. Rosenbaum offers a few tricks and features for finding the ideal sized one-piece.

"I always recommend starting from the bottom and working your way up. You can often adjust the top of a one-piece, but the bottoms are usually a bit more rigid, So if you're a medium on bottom and a large on top, go for the medium suit, and shop a style that features a top that can be loosened," says Rosenbaum. "Lean into your coverage preference. If you like less coverage, you won't mind the added cheekiness and exposure of a smaller suit."

How do I style a one-piece so it feels modern and trendy?

Swimsuits aren't just for the water. Whether you are going from brunch to the beach or dressing up for a pool party, a one-piece can easily become the foundation of a summer outfit. And with all the stylish offerings today, you can wear your favorite one-piece as a body suit for a night out. All you need is the right accessories to complete the look.

"I love piling on accessories like beaded necklaces, belly chains, and beach totes to pull together a whole look. A sheer coverup or pareo also elevates any swim costume," says Rosenbaum. "Denim, whether it be a high waisted jean or a '90s style jacket, takes your one-piece to a whole other level for off the beach wear. And, if you're feeling extra bold, you can style your favorite one-piece over a longer sleeve top for a chic layered look."
