Top 10 One-Piece Swimsuits for the Warm Weather

Let’s get one thing straight: summer ain’t the time to be fussin’ with swimwear that needs constant adjusting. Nobody—and I mean nobody—wants to spend a beach day yanking up straps or pulling down wedgies. That’s why the mighty one-piece swimsuit is queen.

Now don’t go thinkin’ one-pieces are for shy girls or just for “modest” moods. Nope. They’re powerful. Bold. Sometimes a little cheeky. Sometimes drippin’ in elegance like a poolside movie star in the 60s. And when the heat’s cranking up and your iced tea’s sweatin’ harder than you, you wanna feel cool, tucked in, and drop-dead cute in a one-piece that gets it.

I’ve gone and done the scrollin’, try-ons, and the weird sunburn tests—so you don’t have to. Here are the top 10 one-piece swimsuits that’ll make you feel some kinda way this summer.

1. The Hunza G Classic Square Neck One-Piece

This thing? It’s basically swimwear royalty. Worn by models, moms, and that cool girl who only eats citrus in July.

The crinkle fabric is stretchy like, stretchy-stretchy. It fits sizes 6 to 16 without blinkin’. And no zippers. No clasps. Just pull it on and vibe. It’s one of those suits that becomes your body, but in a respectful way, ya know?

Color game? Immaculate. Pick neon, black, sea moss—whatever your summer flavor.

2. Summersalt The Sidestroke

They say it’s the most flattering swimsuit on the internet. The people (mostly women who leave detailed reviews at 2am) agree.

Asymmetrical shoulder. Compression that doesn’t make you feel like a tightly packed croissant. It holds you in without making breathing a challenge. That’s rare.

Also, the color-block combos? Kinda addictive. Like, one minute you’re buying one, the next thing you know, you’re checking out with three and justifying it by yelling “I HAVE A BODY!”

3. Solid & Striped The Nina Belted Swimsuit

You ever wanted to look like a Bond girl… but like, at a Palm Springs pool party where there’s also watermelon margaritas?

This is her.

The belt cinches that waist just enough to make you feel like you’ve got secret agent energy. Fabric feels expensive. And the shape? So timeless it could probably star in a French art film.

It is a little more of a “let’s lounge not dive” vibe, but sometimes that’s the assignment.

4. Andie The Amalfi One-Piece

Not everyone wants spaghetti straps. Some of us wanna feel locked in, covered, and like we could maybe chase a toddler or cannonball without flashing the whole beach.

Amalfi is for those days. Full coverage in the back, scooped in the front. Simple but deadly.

The real kicker is the fit quiz they make you do before buying. Feels intense but actually…kinda genius? It gets it right. Like, first-time-right kind of right.

5. Aerie Wrap One-Piece Swimsuit

Aerie Wrap One-Piece Swimsuit

Aerie has been doing the lord’s work for people who wanna look hot without paying rent money on a swimsuit.

This wrap suit is sneaky hot. Like, oh you look cute and also like you meditate and own a dog rescue hot.

The wrap detail at the front gives the illusion of curves, even if you ain’t got ’em. And if you do got ’em—well, they’re about to be admired respectfully.

Price is soft on the wallet too. We love that for us.

6. Norma Kamali Marissa One-Piece

This one? She’s not subtle.

High-cut legs that go way up. Low back that’s basically an open invitation for stares. It screams ’70s supermodel and requires a bit of confidence—or tequila.

But oh man, the confidence it gives you after you put it on?

Whole. Other. Level.

Not ideal for beach volleyball, unless you like things flying out. But for tanning and slow walks along the shore? Chef’s kiss.

7. J.Crew Ruched Bandeau One-Piece

Sometimes you want classic. No weird straps. No peekaboo cutouts. Just a solid “I’m grown and I still got it” kinda vibe.

J.Crew’s ruched bandeau is that suit.

Ruching hides everything you think needs hiding, but the shape still makes you feel snatched. Comes with detachable straps in case you’re tryna avoid tan lines that scream “I wore a straitjacket to the beach.”

Also… sizes go up to 24. Thank god for that.

8. Faithfull The Brand Costa One-Piece

Faithfull The Brand Costa One-Piece

For when you want your swimsuit to whisper “I read books in hammocks” but still show a lil’ somethin’.

This suit is lightweight, earthy, and breezy. Faithfull’s vibe is very “I thrift, I surf, I plant herbs on my balcony,” and the Costa one-piece just wraps all that up in one wearable mood.

The prints are subtle and summery. And the cut? Not too much. Just enough.

Put it on with a linen sarong and you’ll look like you got a travel blog, even if you’re just in your backyard kiddie pool.

9. Eres Les Essentiels Aquarelle Swimsuit

Luxury. With a capital L and maybe an accent mark too.

This suit will cost ya. It will. But when you feel that fabric? You get it.

Eres makes swimsuits that are somehow simple and absolutely extra at the same time. Like, no prints, no frills, but they fit like they were stitched directly onto your soul.

Not for everyone’s budget, but if you ever wanted to splurge on something that doesn’t feel like a splurge after you wear it—this is the one.

10. Target Kona Sol High Neck One-Piece

Target Kona Sol High Neck One-Piece

You didn’t think I’d forget Target, did you?

This suit slaps. For under $40, you get something that looks way more expensive than it is.

High neck for coverage. Cute keyhole detail for just a smidge of sass. It’s one of those suits you can wear in a hot tub or to chase your niece across a sand dune.

Also, it doesn’t fall apart after one wash, which, let’s be honest, a lot of budget swimsuits do.

So, What Makes a One-Piece Worth It?

It’s not just about looking snatched—though, sure, we want that too. It’s about how you feel in it. A good one-piece makes you wanna cannonball, dance in flip flops, and eat sticky popsicles without worrying if your top’s shifted north.

Fit is everything. Like, everything everything.

You want the straps to stay put without digging in. The bottom to cover what you wanna cover, not what the brand thinks you should. And the fabric? Please let it dry quickly. No one wants a soggy butt.

Trends to Look Out for This Summer

Cutouts are having a moment. Sides. Front. Somewhere unexpected. They’re fun—but don’t always tan well. Just sayin’.

High-leg cuts are back from the ‘90s and they are NOT shy. They make your legs look ten miles long. But they do require a lil’ confidence… or maybe just the right playlist.

Earth tones are creeping in alongside the brights. Olive, clay, rust—colors that look good even if you haven’t seen the sun in six months.

And belted suits? Still here. Still cute. Still somehow make you feel like you have your life together.

Swimsuit Shopping Tips From Someone Who’s Tried ‘Em All

If you’re shopping online (and let’s be real, you are), read reviews like they’re love letters. People will tell you exactly what works and what doesn’t. Trust the person who posted three pics and said “I have a short torso and this fit perfect.”

Order two sizes if you can. Return the one that doesn’t fit your soul.

Also…move around in it. Sit down. Raise your arms. Pretend to pick up a pool noodle. If it passes the noodle test, it’s a winner.

Final Thoughts Before You Hit “Add to Cart”

Swimsuits are weird little garments. Tiny pieces of fabric that somehow have the power to change how you feel about your body in, like, five seconds flat.

But a great one-piece? It doesn’t try to hide you. It wraps around you like a best friend who says “you look freaking amazing, btw.”

So don’t wait for the beach invite. Buy the suit. Wear it to the balcony. The driveway. The grocery store if you must. The heat is here, baby.

And you? You’re ready.

Now go jump in.
