Few wardrobe categories punish poor quality the way swimwear does. This is why luxury swimwear isn't an indulgence — it's the most easily justified piece of designer clothing you can own. Chlorine bleaches the colour out of cheap fabric, salt water warps the elastic, and a badly cut bikini will not survive a single jump from a yacht.
Below are the ten best luxury swimwear brands worth investing in for summer 2026, all of them currently in stock at Klosmo. The list ranges from Saint Laurent and Gucci at the top of the market to Tory Burch and Jil Sander at a more accessible — but still unmistakably designer — price point. Every brand here has earned its place through a combination of fabric, fit, and the kind of design DNA that doesn't go out of style after one season at the beach club.
1. Is luxury swimwear worth it?
In a word, yes — and the reasoning is more practical than aesthetic. A €400 luxury swimsuit can outlast ten €40 fast-fashion bikinis, which means the per-wear cost of the luxury option is often lower across a five-year horizon. Designer swim brands use chlorine-resistant lycra blends, double-lined construction, and sculpting fabrics like Eres' patented Peau Douce, all of which are engineered to hold their shape through years of pool, sea, and sunscreen.
Fit is the second argument. Cheap swimwear tends to gape at the bust, ride up at the leg, and lose its support after one wash. A well-cut designer suit is engineered around a real woman's body — the cup architecture is properly graded, the leg openings are cut to flatter, and the underwire (where used) is shaped to support rather than dig in. For most women who buy a luxury swimsuit once, the experience is unrepeatable in cheaper pieces.
The last argument is psychological. A designer swimsuit photographs differently. It carries differently in a beach bag. And it gives the wearer the small but real confidence of knowing she's wearing something considered, made by a house with a hundred-year archive behind it. That's the part of luxury that doesn't appear on the price tag.
2. How to choose a luxury women’s swimsuit
Before scrolling the list, four criteria worth weighing — they're the same ones a personal shopper would apply.
2.1. Fabric
Look for chlorine and salt-resistant lycra, double-lined construction, and UPF protection if you swim daily. Italian and French manufacturing typically signals better fabric quality than mass-market sourcing.
2.2. Fit
European designer brands tend to run small (a 38 is not a US 8). Check whether the brand grades cup sizes independently of the band — the best ones do.
2.3. Silhouette
A trend-led shape will date in two seasons. A classic triangle bikini, scoop one-piece, or square-neck maillot will not. Choose silhouette before print.
2.4. Brand DNA
The best luxury swim pieces look like the brand even without a logo. A Saint Laurent suit looks like Saint Laurent. A Zimmermann looks like a holiday. Buy into a house's identity, not just a single piece.
3. The ten best luxury swimwear brands to shop now
3.1. Saint Laurent
Shop Saint Laurent One-Piece Swimsuit →
If a single brand defines what investment swimwear looks like in 2026, it is Saint Laurent. Anthony Vaccarello has built the modern Saint Laurent on a refusal to over-design — and nowhere is that more visible than in the swim collection, where a deep V neckline and an architectural cut do the work that lesser brands need a logo to do. The white one-piece in the Klosmo edit is the cleanest expression of this idea: no print, no hardware, no surface decoration. It is the suit a woman buys when she has stopped collecting and started editing.
Best for : the investment piece that will outlast every trend.
Price range : €720 - 790
Origin : France
3.2. Gucci
Shop Gucci GG Stretch Jersey Bikini →
Gucci's swim collection is where the house's heritage codes translate most successfully into beachwear. The current edit at Klosmo includes the GG stretch jersey bikini in beige and ebony — where the monogram is woven into the fabric rather than printed across the chest — and a black stretch jersey one-piece that reads as pure architectural restraint. Jersey, rather than the standard lycra used by most brands, gives Gucci's swim its distinctive drape and its longevity. These are pieces designed to age into a softer version of themselves.
Best for : a Mediterranean boat day with a Cabas tote.
Price range : €650–850
Origin : Italy
3.3. Burberry
Shop Burberry Cobb Bikini →
Under Daniel Lee, Burberry has reframed its archive check from logo to heritage pattern — and nowhere is that shift more elegant than on a swimsuit. The Cobb bikini in archive beige and the nylon one-piece in sand check are quintessential modern Burberry: instantly recognisable to anyone who follows fashion, invisible as branding to anyone who doesn't. The check does the work the logo used to do, more quietly. For women looking for a single piece that says British luxury without saying it loudly, this is the brand.
Best for : a coastal weekend in Cornwall, or anywhere with the word "club" in the venue name.
Price range : €500–540
Origin : United Kingdom
3.4. Celine
Shop Celine Jercy Bikini with Monogram Print →
Celine's swim is rare — the maison releases only a small selection each season, which is part of the point. The current Klosmo edit carries the jersey bikini in toffee brown with the Celine monogram print, which manages a difficult balance: the monogram is dense enough to be unmistakably Celine, but the muted brown colourway keeps the piece from reading as logomania. It is monogram swimwear for women who would not, ordinarily, wear monogram swimwear.
Best for : women who buy Celine bags, and want a beach version.
Price range : €490
Origin : France
3.5. Dolce & Gabbana
Shop Dolce & Gabbana Floral Print Swimsuit →
Dolce & Gabbana built its identity on the iconography of Sicily — lemons, baroque florals, Madonna prints, gold filigree — and the swim collection is where that visual vocabulary distils to its most playful. This is the most maximalist brand on the list, and unapologetically so. The Klosmo edit covers everything from sculpted black one-pieces to print-heavy bikinis straight off the Sicilian island shoots. Buy Dolce & Gabbana when you want a swimsuit to be the centrepiece of an outfit, not its accessory.
Best for : a holiday in Taormina, Capri, or anywhere requiring a long lunch.
Price range : €280–750
Origin : Italy
3.6. Etro
Shop Etro Paisley Bikini →
Etro has spent six decades turning paisley into the most recognisable Italian print outside of Pucci — and the brand's swim line is where that heritage gets its most wearable expression. The Klosmo edit carries Etro's signature paisley bikini in floral motif alongside the matching one-piece, both in a colour palette that reads as resort-perfect rather than loud. What makes Etro a smart pick at this price point is that the print itself does the work of luxury signalling: anyone who knows fashion knows Etro paisley on sight, and the muted Mediterranean palette keeps it elegant rather than busy.
Best for : a holiday on the Italian Riviera, or anywhere paisley belongs to the landscape.
Price range : €320–350
Origin : Italy
3.7. Versace
Shop Versace Greek One-Piece Swimsuit →
Versace has never been a quiet brand, and its swim collection has no interest in pretending otherwise. The Greca prints, the gold hardware, the bright Miami colour palette inherited from Gianni — all of it is engineered to be photographed, posted, and recognised. Donatella's current direction has softened the maximalism slightly, with more pastel and butterfly motifs entering the swim line, but the core identity is intact. This is a brand for the woman who wants her swimsuit to do something — visually, socially, photographically.
Best for : a yacht week, a birthday weekend, or anywhere a photograph will be taken.
Price range : €210–410
Origin : Italy
3.8. Zimmermann
Shop Zimmermann Awaken Crochet One-Piece Swimsuit →
Founded in Sydney in 1991 by sisters Nicky and Simone Zimmermann, the brand has spent three decades perfecting one specific thing: the resort wardrobe. Their swim collection is the foundation of that universe — Wanderlust prints in tapestry blue, scallop-edged Cascadian one-pieces, crochet detailing that translates seamlessly from sea to lunch table. Zimmermann is also one of the few brands on this list where the swim and ready-to-wear pieces are designed to be worn together, which makes it a smart entry point for building a coordinated holiday wardrobe.
Best for : a week on the Amalfi Coast, or anywhere requiring more than one swimsuit.
Price range : €130–430
Origin : Australia
3.9. Jil Sander
Shop Jil Sander One-Piece Swimsuit with Logo →
If the rest of this list is about ornament, Jil Sander is the antidote. The German house has spent decades refining a single thesis — that the absence of decoration is its own form of luxury — and the swim collection follows it precisely. White and black one-pieces with clean square necklines, brown bikini briefs in muted ivory, occasional discreet logo placement on the hip rather than the chest. For women whose entire wardrobe leans toward the architecturally minimal, this is the swim brand that will not break the consistency.
Best for : minimalists, architects, and anyone whose holiday wardrobe is mostly white linen.
Price range : €140–390
Origin : Germany
3.10. Rick Owens
Shop Rick Owens Chic Swimwear →
A list of luxury swimwear brands without Rick Owens would be an incomplete portrait of how women dress in 2026. Owens has built an entire universe on the inversion of conventional beauty — long lines, dark palettes, draped fabric, an architectural rather than decorative sense of body. His swim collection is for the woman who wears black to the beach not because she's hiding but because she's certain. The Klosmo edit carries pieces that read as ready-to-wear as much as swimwear, which is precisely the point: this is luxury swim for women who don't see the beach as a separate occasion from the rest of their lives.
Best for : the woman who wears Rick Owens everywhere else, and sees no reason to stop at the pool.
Price range : €270–450
Origin : USA / Italy
4. A note on resort swimwear: MC2 Saint Barth
Beyond the ten luxury brands above, one name deserves a separate mention for a different reason: MC2 Saint Barth. The Italian resort label, founded in 2008 and named after the Caribbean island that inspired its colour palette, occupies a category of its own — not investment-grade luxury, but the unofficial uniform of European holiday culture from Mykonos to Forte dei Marmi.
What MC2 Saint Barth offers is something the brands above don't: a deep selection of bikini styles at a price point that lets a buyer pack three suits for a week away rather than commit to a single statement piece. The Klosmo edit carries everything from the Lora nylon bikini to the Sagittarius viscose-blend top, the Virgo nylon bottoms, and the brand's signature embroidered Sangallo designs — a vocabulary of holiday swimwear that has made MC2 a fixture of European beach clubs for over a decade.
This is the brand to buy alongside a more serious luxury piece, not instead of one. A Saint Laurent one-piece for the days you want to be remembered; an MC2 bikini for the days you want to disappear into the rhythm of the holiday.
Best for: a multi-suit holiday capsule, or anyone who treats swimwear like t-shirts.

Shop Now5. Which luxury swimwear brand is best?
There is no single best luxury swimwear brand — the right choice depends on aesthetic and use case. For investment-grade minimalism, Saint Laurent leads. For pattern as heritage, Burberry. For resort-driven holidays, Zimmermann. For the boldest statement piece, Versace. The list above is structured to help readers find the brand that matches their existing wardrobe, rather than ranking brands against a single criterion that doesn't reflect how women actually buy swimwear.
Luxury swimwear is one of the few designer purchases where the math is unusually clear: a piece that costs ten times the fast-fashion alternative will, if chosen well, outlast it twenty times over. The ten brands above are the ones we believe will earn that math this summer — across price points from Tory Burch's accessible entry to Saint Laurent's investment-piece end of the market, and across aesthetics from Jil Sander's minimalism to Versace's maximalism. Every piece in this edit is currently in stock at Klosmo, with worldwide shipping and the kind of authentication chain you'd expect from a destination of this calibre.
