With summer fast approaching, finding the perfect swimsuit is a tricky task that can leave you drowning in a sea of options.
Whether you're jetting off abroad or are planning on hitting some more local beaches, a good swimsuit or two-piece is a summer staple.
This season, sculptural shapes, retro prints and nostalgic colour blocking are making a comeback according to swimwear experts. Here are their must-try styles for summer 2025.
1. Sculptural and minimal
Sleek, minimal designs with metallic detailing are making waves this season. "There's a resurgence in sculptural silhouettes – elegant one-shoulders, discreet cut-outs and scuba-inspired one-pieces with zip detailing, which I personally love," explains fashion designer and podcaster Amanda Wakeley.
There also seems to be a rising trend for swimwear that transitions beyond the beach, like pairing costumes with maxi skirts and sarongs for an effortless, White Lotus- inspired look.
"Statement one-pieces are taking centre stage," agrees founder and creative director of Baíah, Tracy Nahar, "with details like asymmetrical necklines and sculpted corset-style shaping."
Nahar points out the return of textured fabrics, leaning into the resurgence of the Eighties trend, "crinkled Lycra and ribbed stretch materials not only elevate the look but also contour beautifully to the body."
2. Retro revival and colour blocking
Colour blocking with bright, mood-lifting colours seems to be back this summer.
"There's a real shift toward mood-lifting colour," says founder of Paper London, Philippa Thackeray, "sunshine tones like lemon, coral and cobalt are big, but it's not just about brights – there's nuance.
"Rich navy, soft pastels and pops of retro colour blocking, with gingham being big too," says Thackeray.
It's not just the colours of the Eighties that are big in swimwear this season. "Square necklines, higher leg cuts and underwired classics," are seeing a strong revival, explains swimwear design manager at Pour Moi, Vicky Chadeyron.
"Bold ocean blues are another major player, a gorgeous and flattering colour," she says. Other Eighties prints like polka-dots are also trending this season.
3. Figure flattering styles
Finding flattering swimwear can feel like a never-ending pursuit, summer after summer. While it's specific to your body shape, there are some universal styles that can flatter any figure.
"One of the most flattering styles across body types is a plunging neckline, which draws the eye vertically and creates a lengthening, slimming effect," explains Thackeray.
Ruche and wrap details are also good options for those conscious of their stomach, with belted details and wrap styles helping define the waist.
"Surprisingly, I think a string bikini can be incredibly flattering for all body types – the key is adjustability," says Wakeley.
"It's less about size, more about how it makes you feel – and confidence is always the most flattering look of all. Drawstrings on one-piece swimsuits allow for a degree of customisation of fit and add a soft drape, which is generally very flattering."
4. Styles that aren't just for Instagram
While strapless styles and cut-out detailing may be trending – functionality is just as important as fashion when it comes to swimwear.
"There are so many beautiful suits out there that just don't hold up once you actually get in the water," laughs Thackeray.
Excessive cut-outs and barely-there straps seem to be the main culprits, "[they] might look amazing online, but in real life they can be restrictive or high-maintenance," she says.
Other, more wearable trends can be just as impactful. "A single dramatic strap or a modest cut-out [can] bring the same impact without compromising comfort," says Nahar.
Trying on a range of styles – as opposed to blindly ordering what looks good online – is the best way to find the perfect shape for you. "Swimwear should move with you, not against you," says Wakeley. "Make sure it fits well and stays in place, otherwise you will be spending way too much time re-positioning it."
