The sun is shining, vacations are booked, and bathing suit season is finally here. It’s the perfect time to refresh last year’s swim wardrobe with the best one-piece swimsuits for summer 2023. We see one-piece swimsuits get elevated each season. The runways at Miami Swim Week 2023 hinted toward one-piece silhouettes in a range of intriguing hues and cuts at brands like Acacia and LainSnow.
“We are seeing more design details transferred across from ready-to-wear collections,” explains Libby Page, Market Director at Net-a-Porter. “For instance, Christopher Esber’s signature cutouts, once featured on dresses alone, can now be found in the brand’s swimwear offerings.”
While one-piece bathing suits can simplify swimwear, they don’t have to be aesthetically boring or worn purely for function. Pamela Anderson’s red “Baywatch” swimsuit is arguably the most iconic swimsuit in pop culture history. In recent years, sporty styles of high leg cuts and skin-skimming fabrics have renewed demand — Anderson now has a collection with Frankie’s Bikinis, including styles inspired by her ’90s suit. These days, one-piece swimsuits are rivaling the bikini for coolest swimwear trend — thanks in many ways to innovative new takes on designs from top brands on the market including Skims, Andie Swim, Solid & Striped, Eres, and more.

With more fashion-forward brands putting a unique spin on the one-piece, key points to consider when shopping for your new favorite suit for the season is where you’ll wear it and what activity you’ll be doing — whether you’re looking forward to a low-key beach vacation with your designer beach bag in tow, or plan on taking up a water sport this summer. Some one-pieces are designed to prioritize comfort and offer more coverage (think long-sleeved and underwire silhouettes) while others are intended to make a bold statement by way of cutouts — or even a thong bottom. “It’s less about ‘what works for your body type’ and more about what you feel good wearing,” explains Ginger Lau of Solid & Stripe’s design team.

On the hunt for a stylish swimsuit that still offers comfort and coverage?

The adjustable drawstrings on either side also make this suit easily adjustable depending on how high-cut you prefer the leg of a suit to be.
What reviewers say: One customer said, “I love this swimsuit. I’m normally a medium/large, so I got a medium because I like a smaller one-piece. This suit doesn’t cut into my body at any spot. The top is a lower cut scoop, which is very flattering. The most flattering part is the adjustable, rouched sides. You can make the sides as low or high cut as you want with the sides. I like a higher cut, so it was perfect to be able to adjust. Plus the rouching on the tummy looks awesome. Highly recommend!” Another said, “I went back and forth on whether or not to buy this suit.

Laya Swim Downstream One-Piece Swimsuit
Best Red One-Piece Swimsuit
- Materials: Polyamide, lycra
- Special features: Wired V-neckline, adjustable criss cross back
Don’t let a fear of tan lines keep you from testing out a swimsuit with a playful cut. Laya’s deep V-neck style has a wired front to keep the swimsuit fitted to the skin. It also features a lace-up back that not only offers adjustability but also a playful design touch that takes this style to the next level.
What reviewers say: One customer said, “Love this full piece swimsuit. The deep V is super sexy but I still feel supported. Love that the straps are adjustable and it has great coverage. Super flattering!”
The Different Types of One-Piece Swimsuits
- Halter: For a simple, classic swimsuit option, a halter style fits the bill. It ties behind the neck, which allows for adjustability, and may also have a scoop back or waist tie details.
- Cutout: A more trend-forward option, cutout one-pieces come in many forms. When trying out a one-piece with cutouts, make sure to move around in it to ensure it offers coverage where you want.
- Strapless: If you’re worried about tan lines, you may want to consider a strapless one-piece. It’s not the most supportive option of the bunch, so you’ll want to make sure it doesn’t slip down before wearing it out.
- Sporty: Looking for a suit designed specifically for swimming or a game of beach volleyball? Look for simple silhouettes with technical fabrics and supportive straps. Avoid anything that will ride up or get in the way.
- Plunge: A low-cut one-piece is a great option if you’re looking for something you can transition to wearing with everyday clothes. The deep-V neckline is the defining design element of this suit.
- ’90s-Inspired: “Recently, we’ve been feeling for ’90s silhouettes,” Lau says. “We love their high-cuts and versatile end-use. Iconic swim images from the ’90s of supermodels like Cindy Crawford, Naomi Campbell and Linda Evangelista serve as constant inspiration.”
What to Look for in the Best One-Piece Swimsuits
- Material/Fabric: One-piece material options will depend on the your functional and aesthetic needs. If you want an ultra-flattering swimsuit to wear all summer, look to suits with materials like nylon, mesh, elastane, or spandex that have smoothing technology similar to shapewear. Page says, “If you’re looking for something more technical, look for styles in neoprene with supportive racerbacks.”
- Fit: “Consider what it is you want from a one-piece,” Page says. “If you’re looking for something body-sculpting or leg-lengthening, try styles with front darts and high-cut designs,” says Page.
- Padding: Depending on your cup size, padding will be a key element to consider in choosing a one-piece suit. If you need more support, choose a suit that has a built-in bra or underwire, as well as thick straps. Many one-piece styles offer the option for removable padding to customize your level of support depending on your chest size.
- Lining: One-piece suits with thin lining will be form-fitting and skin-tight. They may appear sheer in pale colorways, creating a sexy, nearly-naked affect from your swimwear. If you’re looking for a one-piece with more compression and smoothing capabilities, choose a suit that has thicker lining.
- Price: When it comes to swimwear, the price often reflects the level of support, quality of fabric, and fit. Investing in a one-piece that offers UPF protection, thick lining, bra support, and aesthetic satisfaction will last you for many summer on end and hold up in water sports.
One-Piece Swimsuit Trends for 2023 and One-Piece Swimsuit Outfit Ideas:
Long sleeves: Believe it or not, long-sleeve one-pieces are a major swim trend for 2023. They protect the arms from UV rays while keeping you warm in cold water. At Miami Swim Week, sheer and opaque long-sleeves were shown at Swim With Poppies, Haitian Doll by Jo Bella, Pac Sun, while long-sleeve swim shrug gloves sold out at Skims.
Barbiecore pink: Vivid pinks and bubblegum hues remain a swimswear trend for 2023 – plus, it’ll make your vacation glow pop. We’ve seen Barbiecore pink from brands like Skims and Athleta, as well as on the Miami Swim Week runways from Kass, Gengi Swimwear, JAMS by Jillian, Amarotto Swimwear, and Banana Moon. Pink is never out of style and a one-piece suit can wear similarly to a body suit in cute summer outfits like cut-off Levi’s 501 shorts and matching Barbiecore shoes.
Mermaidcore shimmer and metallics: Shiny, colorful swimsuits that make you look like you just washed ashore are trending this summer, from brands like Oséree, Wear Daydream, Aqua Blue Beachwear, and Brasilia Swim. Any skin-skimming suits that shimmer like the sun over water, with glitter, scales, jewels, or nautical embellishments and flattering ruching will surely make a splash in your swimwear rotation for 2023. Style your aquatic suit with a designer beach bag and a string of pearls for an under-the-sea statement.
Cutouts: Clever, sexy cutouts always always elevate one-piece styles. They accentuate curves with strategic cuts that give more security than what a regular two-piece can offer. Swimwear brands such as ByCassandre, Diva Kurves Co., Hunza G, and Bound By Bond-Eye are leading the charge in flattering one-piece skin slits this summer. Cutouts speak for themselves, so these suits pair best with simple sandals, minimalist jewelry, and a chic designer tote bag.
High-Cut Legs: One-piece swimsuits that feature high leg cuts accentuate the hips and make your legs look like they go on for miles. They also work to secure the midsection like a high-waisted pant, give just the right amount of cheeky bum coverage, and create an overall hourglass body shape. We’re seeing these styles from brands like Aerie, Eres, and Normal Culture x Jelaminah. Since this cut elongates your sea legs, stick to footwear that omits high strapping, like slingback mules, platform sandals, or colorful slides.
How to Know Your Swimsuit Size
Shopping for a one-piece swimsuit online can prove tricky — looking at reviews from previous customers can help you find any discrepancies in sizing. Also, when you first try a new swimsuit on, make sure you test it by doing some stretches and general movements to get a sense if it rides up or pulls in the wrong places. Since different suits can be designed for swimming, beach sports or simply lounging, make sure that the suit fits the bill.
Also, since sizing can be so different from brand to brand, make sure to take your measurements at the bust, waist and hip so that you can compare your measurements on a size chart and ensure that you’re choosing a suit that best fits your body.
