Designer one piece swimsuits have quietly taken over the resort pool, and the reason is practical rather than aesthetic. A well-built maillot holds its shape through salt water, sunscreen, and a hundred loungers, while a cheap one sags at the leg openings by day four.
The sixteen suits below span roughly $30 to $380, and every one of them earns its spot for a specific reason — Italian swim fabric, chlorine-resistant LYCRA Xtra Life, gold-tone hardware that reads as jewelry, or a cut that photographs well without a single adjustment.

1. J.Crew Long-Torso Nia Ruched Squareneck
The J.Crew Long-Torso Nia Ruched Squareneck One-Piece in Gingham solves a problem most brands ignore entirely, which is that tall women and long-torso women have spent years defaulting to bikinis because one pieces simply do not reach. The squareneck is supportive without being severe, subtle ruching runs down the sides to add dimension and shorten the visual line of the torso, and the suit is built from at least 30% recycled materials with removable pads and a high-rise back. Reviewers call it slimming through the belly and note the higher leg cut lengthens the legs, though the fabric has very little give — size up if you are between sizes.

2. Victoria’s Secret Beaded Lace-Up Brazilian
The Victoria’s Secret Beaded Lace-Up Brazilian One-Piece is the least practical suit on this list and makes no apology for it, finishing lace-up detailing with shiny metallic beads across a body-skimming cut. Victoria’s Secret builds this in their customer-favorite swim fabric — soft, stretchy, and built to hug rather than compress — with Brazilian-cut coverage at the back that shows more than it hides. Buy it for the vacation photographs and the drinks after, not for the day you plan to go in past your knees.

3. Abercrombie & Fitch A&F Isla
The A&F Isla One-Piece Swimsuit has quietly become one of Abercrombie’s most reliable swim sellers, built on a plunging deep-V neckline with an O-ring hardware detail at the center and fully adjustable ties at the neck. That last feature is the one that matters — you set the depth of the plunge yourself, which turns a risky neckline into a wearable one for a much wider range of bodies. It comes with removable pads for light support and a high-leg cut with cheeky coverage, and customers consistently report it runs true to size.

4. Shapellx Plunge Ruched Twist-Front
The Shapellx Plunge Ruched Twist-Front One Piece is shapewear disguised as swimwear, and the disguise is convincing. Supportive mesh fabric cinches through the waist, abdomen, and back, a twisted knot at the waist conceals the midsection where most suits merely stretch across it, and the built-in removable cups add lift with no separate bra required. The crisscross straps convert three ways — V-neck, one-shoulder, or front-cross — so a single suit covers three different looks over a week-long trip.

5. Beach Riot Stassia One Piece
The Beach Riot Stassia One Piece is a strapless silhouette that arrives with removable, adjustable straps, so you get a bandeau, a classic strapped suit, and a bodysuit out of one purchase. Beach Riot builds it properly — boning at the sides to hold the strapless shape, a tie-back closure, gripper tape along the bust that actually stops the slippage, and lined cups with removable padding. The shell is 80% nylon and 20% elastane, and the brand pitches it as a suit you wear poolside and then style with denim or boots at night, which is not marketing hyperbole in this case.

6. Nili Lotan Embellished Swimsuit
The Nili Lotan Embellished Swimsuit is the black suit you buy once and keep for a decade, punctuated with signature gold-tone hardware at the center and detailed with soft ruching that shapes without shouting about it. The straps are adjustable and removable, which converts it from a strapped suit for the beach to a clean strapless line for the terrace in about four seconds. Nili Lotan launched her label in 2003 after leading design teams at Ralph Lauren, Liz Claiborne, and Nautica, and this suit is exactly what that résumé sounds like in swimwear.

7. Cupshe Feel the Rush Black One-Piece
The Cupshe Feel the Rush Black One-Piece trades hardware for texture, finishing a plain black suit with scalloped edges along the leg openings and neckline that catch the light the way a good trim should. A V-neckline and adjustable straps set the fit, and removable soft cups deliver light bust support — enough for lounging and shallow water, not enough for anyone planning to bodysurf. The scalloping is the whole point, and it’s the detail that separates this from every other black suit on a crowded pool deck.

8. La Blanca Island Goddess One Piece
The La Blanca Island Goddess One Piece is the brand’s best-selling swimsuit and it holds a 4.8-star average across more than 1,200 reviews, a number very few swimsuits reach at any price. The construction is deliberate — 83% nylon and 17% elastane, shirred side seams that give the midsection room without clinging, removable cups, adjustable straps, and moderate rear coverage with no underwire anywhere in the build. Reviewers who swim laps mention the shirring specifically, and it runs a little short in the torso, so tall shoppers should size up.

9. Cupshe Gold Standard Black One-Piece
The Cupshe Gold Standard Black One-Piece earns its name — solid black, clean lines, gold hardware as the only ornament, and around $35.99 on the sticker. Black swimwear either looks expensive or looks cheap, and the difference is almost always the finish rather than the fabric, which is where the metal detailing does its work here. This is the suit that goes under a linen shirt for a beach lunch and comes back out for the pool an hour later without a second thought.

10. Ulla Johnson Milos Floral O-Ring
The Ulla Johnson Milos Floral O-Ring One-Piece is cut from Italian swim fabric and made in Portugal, saturated in baroque florals arranged in symmetrical motifs — the kind of print that looks hand-painted rather than repeated. A plunging halter neckline is centered with a stone-embellished O-ring at the bust, the back opens completely, and an adjustable hook closure at the neck lets you set the drop of the V exactly where you want it. It’s 80% polyamide and 20% elastane with a full lining, carries a $360 retail price, and offers cheeky coverage — a suit for the terrace and the photographs, not for the lap lane.

11. Tommy Bahama Island Cays Color Block
The Tommy Bahama Island Cays Color Block Tie Front Tummy Control Tank One Piece does its quiet work with targeted front panel compression rather than an all-over squeeze, so the shaping sits exactly where it’s needed and nowhere it isn’t. The tie front detail breaks up the midsection and, per the reviews, camouflages a belly better than any print does, while molded cups and adjustable straps give the bust real lift and a tank silhouette keeps it wearable at a hotel pool. It’s cut from textured recycled nylon and spandex with UPF 50 sun protection, and the side-panel color blocking creates a vertical slimming line that’s genuinely visible in photographs.

12. Lands’ End Tugless Low Leg One Piece
The Lands’ End Women’s Plus Size Tugless Low Leg One Piece is named for the problem it solves — no creeping, no digging, no adjusting behind a towel — and it delivers that through wide shoulder straps that stay put and a high scoop neck front and back that never needs a second thought. The fabric is 77% nylon and 23% LYCRA Xtra Life spandex, rated to last up to ten times longer while resisting breakdown from chlorine, sunscreen, and sweat, with UPF 50 sun protection built in. A soft cup bra handles support without underwire, built-in shaping smooths the waist and hips, and the lower cut leg openings give real coverage — this is the suit for lap swimming, water aerobics, and any vacation day that involves actual swimming.

13. BAR Going On All The Trips One Piece
The BAR Going On All The Trips One Piece Bathing Suit is the closest thing here to a genuine do-everything suit, cut in solid black with clean lines that read expensive from ten feet away and don’t fight with a cover-up. Black hides everything, dries fast, and survives being stuffed damp into a beach tote at the end of the day, which is more than most printed suits can claim after a season. Pack it as the one you wear on travel days and the mornings you have not decided what the day looks like yet.

14. American Beach Babe One Piece
The American Beach Babe One Piece Bathing Suit leans hard into stars and stripes, and it earns its place in the suitcase for exactly one reason: it owns Fourth of July, Memorial Day weekend, and every lake trip in between. The high-cut leg and strappy back keep it from tipping into costume territory, which is the trap most flag-print swimwear falls into around the second beer. Buy it for the holiday weekends and let the black suits handle the rest of the calendar.

15. Cupshe Sheer Thing One-Piece
The Cupshe Sheer Thing One-Piece builds sheer mesh panels into an otherwise solid black suit, giving you the visual break of a cutout without any of the tan lines or the sunburn in strange places. Cupshe’s swim fabric runs around 80% nylon and 20% spandex with removable soft cups, so the bust support adapts to what you’re doing rather than committing you to one shape. Black plus mesh is about as safe a place as designer-adjacent risk-taking gets.

16. Nili Lotan One Piece Bathing Suit
The Nili Lotan One Piece Bathing Suit sits around $295 to $310 and does everything quietly, starting with signature gold hardware — a U-link and clasp closure that reads as jewelry rather than trim. It’s underwire-free with shirring at the front and adjustable, removable straps, so it converts from beach to terrace without a second suit. The vintage leopard print is the version worth buying, restrained enough to wear at forty and at sixty without a second thought.

Sixteen suits, roughly a ten-fold price spread, and not one of them chosen for the label alone. Lands’ End, Tommy Bahama, and Shapellx earn their keep on engineering, Cupshe and La Blanca on value, and Nili Lotan and Ulla Johnson on the details you notice on the twentieth wear rather than the first.
