The Best Designer Swimwear Brands (2026)

There is a particular cruelty to designer swimwear: you pay couture prices for a few grams of nylon, then expose it to chlorine, salt, sun cream and the unforgiving honesty of poolside photography. So the question is not whether a label is fashionable. It is whether the thing survives the summer, flatters a real body, and still looks like money after twenty washes. We have opinions — strong ones — and below is our unsentimental ranking of who actually earns the spend in 2026. For the broader field beyond the luxury tier, see our best swimwear brands of 2026; if you want the economic argument for spending at all, our piece on swimwear as investment makes the case better than any price tag.

Hunza G

The crinkle-fabric cult that refuses to die, and rightly so. Hunza G's genius is the one-size-fits-most seersucker, which sounds like a gimmick until it clings to you like it was cut to measure and then springs back to shape the moment you stand up. It is the rare designer label that is genuinely forgiving — it does the flattering for you. The colour palette is impeccable, the silhouettes are nostalgic without being costume, and resale value is absurdly strong. The catch? Coverage is minimal and the "one size" ethos has its limits at the extremes of the range. For everyone in between, it is the closest thing to a guaranteed win. Best for: the woman who wants to throw one piece in a weekender and look considered. Browse our Hunza G edit or Shop Hunza G.

Melissa Odabash

The grande dame of grown-up glamour, and the brand your most polished friend has been wearing in Capri for years without telling you. Odabash understands structure — the underwiring is real, the necklines are engineered, and the cover-ups are doing eighty per cent of the styling work for you. This is swimwear for people who want to look expensive rather than fashionable, and the distinction matters. It is not cheap and it does not chase trends, which is precisely the point. Best for: the confident over-thirties dresser who treats the pool as a venue, not a sport. See our Melissa Odabash selection or Shop Melissa Odabash.

Zimmermann

Maximalism with a couture pedigree. Nobody does a print like Zimmermann — the florals are painterly, the ruffles are architectural, and the whole thing photographs like a holiday advert. You are paying for the design house, not the fabric weight, and you should know that going in. The fit can run idiosyncratic and the price is frankly heroic, but for sheer presence on a beach in Puglia there is no equal. This is the brand that makes other people ask where you got it. Best for: the romantic who wants their swimwear to be the outfit. Explore our Zimmermann picks or Shop Zimmermann. It pairs beautifully with the kaftans in our luxury resort wear guide.

Monday Swimwear

The influencer-founded label that quietly grew up. What began as an aspirational social-media project has become a genuinely well-made line, and the fit consultancy shows: the cuts are flattering across a wide range of shapes, the fabric has weight, and the neutrals are exactly the muted tones that read as quiet luxury. It is not the most original brand on this list — you will not turn heads with the silhouettes — but it is dependable in a way that justifies the mid-luxury price. Best for: the buyer who wants understated, body-confident pieces without the couture markup. See our Monday Swimwear edit or Shop Monday Swimwear.

Frankies Bikinis

Unapologetically Californian, unapologetically tiny. Frankies is the brand for the young, the tanned and the confident — the ruched bandeaus, the string ties, the sugary palette. When it is good it is very good, all playful and sun-soaked. When it is less good, the coverage is so minimal it borders on theoretical, and the construction can feel light for the price. Buy it for the fun, not the longevity, and go in clear-eyed about how much skin you are committing to. Best for: festival-season hedonists and anyone whose holiday involves a yacht. Browse our Frankies Bikinis picks or Shop Frankies Bikinis.

L*Space

The quiet overachiever of the mid-luxury bracket. L*Space gets less press than the loud labels above, but the reversible pieces, the genuinely supportive tops and the clever convertible straps make it one of the smartest value propositions in the category. The aesthetic is breezy and Californian without tipping into Frankies territory, and the build quality outpaces the price. If you want one brand that simply works — flattering, durable, sensibly cut — this is the unflashy answer. Best for: the practical glamour-seeker who resents paying for a logo. See our L*Space selection or Shop L*Space.

The True Luxury Tier: Eres & Eberjey

And then there is the rarefied air. Eres is the Parisian benchmark — the fabric is thick, sculptural and matte, the cut is mathematically precise, and the price will make you gasp. There is no print, no fuss, only the most flattering plain swimsuit money can buy, and it lasts for a decade. Eberjey occupies the softer, slinkier end of the same neighbourhood, prized for buttery fabrics and a barely-there sensibility that feels like lingerie for the sea. Neither shouts. Both are what you graduate to once you have stopped caring whether anyone recognises the label. Best for: the minimalist who has decided, finally, to buy once and buy properly — exactly the philosophy we argue for in our swimwear investment piece.

The verdict, then: if you want a single safe purchase, buy Hunza G. If you want to look quietly rich, buy Eres. Everything in between is a question of how much theatre you want and how much skin you are prepared to show. Choose accordingly — and never, ever sit on a sun lounger without a towel.
