22 Low-Back Swimsuits for Showing a Little Skin

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links."

The sun is hot. The pool is cool, blue, and awaiting your crisp dive in. In this moment, the last thing you want is a swimsuit that’s going to bunch, twist, or even tug off as you make your big entrance. As an alternative to a bikini, consider the best low back one-piece swimsuits, styles that show off a bit of skin while still remaining snug whether you’re swimming laps or simply sunbathing.

These revealing one-piece swimsuits are a go-to choice for style experts like Alison Bruhn, co-founder of The Style That Binds Us. "Since you’re wearing a one-piece, the suit will have more coverage anyway, so it’s nice to have the back showing a little extra skin," she explains. "It’s a very graceful look with the eye following the curve of the back." When you’re done swimming, these suits can do double duty as a top—no need to throw on a bunch of soggy layers. Bruhn suggests styling yours with a skirt or shorts if you’re headed out. "It’s really pretty to have a sarong tied at the waist or hip, because then, even when you’re wearing your cover-up, the elongated back area can still be a focal point," she adds.

Just like any vacation swimwear, fit will make the difference with a low-back one-piece. Shoppers with a long torso should consider ordering a size up, as sometimes suits may be too short (though the brand Left On Friday featured below, includes a tall sizing option). Also, keep in mind the cut of the suit. For those with fuller chests, you’ll still want to make sure you’re supported with thick straps or even a bustier-style design.

Whatever your size or poolside style, shop the 22 best one-pieces designed to show off your back ahead.

Low Palace One-Piece Swimsuit

The name Bond-Eye is a play on the famous Australian suburb Bondi Beach, where this brand’s suits are made. This style is made of comfortable, crinkled fabric, and has adjustable straps, a feature that you don’t always find in one-piece swimsuits.

Color: Bronze, pink, green, purple, black

Material: 46% nylon, 38% polyester, 16% lycra

What reviewers are saying: "I have literally never, in my 26 years, felt hot in a swimsuit...until this one. I took mirror selfies, ran around the beach and just generally felt amazing in this bad boy."

Holiday One Piece

This Zonarch style comes recommended from Bruhn. "I love that it’s low enough in the front to feel glamorous, and low in the back too, but it still gives you plenty of coverage and holds you in," she says. "This brand is sustainable and affordable and very well-made."

Sizes: XS-XL

Color: Black

Material: 74% recycled nylon 26% spandex

What reviewers are saying: "I feel confident, strong, and sexy in this suit! It fits perfectly in all the right places, and is still comfortable enough to surf in."

Sizes: 1-5

Color: Blue

Material: 80% recycled nylon, 20% elastane

What reviewers are saying: "The swimsuit really compliments the figure, snatches the waist, and elongates the legs. The scoop neck might look quite low if you have small breasts."

Printed Underwire One-Piece

Color: Pink

Material: 71% nylon, 29% lycra

Material: 82% nylon and 18% spandex

What reviewers are saying: "It's the best one-piece I've ever had. I was looking for a cross-back style with a low back. I like the combination of support and exposure to the water. The cut of the leg is just right, as is the neckline."

Swim Straight One-Piece

For a casual trip to the coast, use a black swimsuit in the same way you’d style a sleek bodysuit. Try throwing one on with denim cutoffs.

Sizes: XS-XL

Color: Black

Material: 80% nylon, 20% elastane

What reviewers are saying: "My husband gifted this one-piece swimsuit with the pareo. It’s a beautiful set. One thing I would say, take one size up as it runs small and be mindful that if the torso is short it’s because you wear this swimsuit high."

The Gabby
