Swimwear is always a focal point of any summer wardrobe, however in the spring/summer 2025 collections swimming costumes weren't just for the beach and lidos, but were also styled for chlorine-free city days. At Miu Miu brightly coloured swimsuits with cut-outs were worn like bodysuits with pleated midis and patent leather pencil skirts, while at Tory Burch black streamlined swimsuits you’d typically see in London’s Aquatic centre were worn with tailored trousers instead of swimming caps and nose plugs. This unlocked the styling potential of the humble swimsuit, proving they should be given more attention than being a pre-flight “this will do” purchase.
A black swimsuit will always be a stylish, classic purchase, however if you are looking to dive into new territory, there are a number of swimwear trends causing a splash this summer. After years of minimalist suits, five-star resorts are about to be inundated with designer swimwear with a more-is-more White Lotus energy, that couldn’t possibly be mistaken for a H&M lunchtime purchase. The Burberry checked bikini has had a significant marketing push for 2025, with Rosie Huntington-Whiteley diving off a yacht in her plaid, stringy set in the high summer campaign. Missoni zig zags, Chanel hardware, Pucci swirls and Gucci heritage prints are also riding the wave of this post-quiet luxury approach to beachwear.
Miu Miu has also had a significant influence over summer 2025 swimwear trends with sporty bikini tops and briefs that have a contrast piping trim. It’s a subtle detailing that you’ll see across new-in sections, from monochrome suits to more punchy colour combinations. Decorated swimwear is also making its way to a sun lounger near you, as simple swimsuits are adorned with corsages and metal hardware.
Whether you’re heading to Ibiza or your local lido, ahead find 8 swimwear trends that are making ripples this summer.
2025'S BIGGEST SWIM TRENDS:
1. Designer Logo Swim
Style Notes: Resortwear has been steadily rebelling against the quiet luxury movement, with looks that are as flamboyant and colourful as a cruise cocktail menu. Luxury brands such as Burberry, Pucci and Gucci are leaning into their heritage prints, with swimwear inspired by the archives. Forget subtlety, this is all about dressing like you are Kris Jenner spending your summer yachting your way around the Med. Don’t limit the logo-dropping to just the swimsuit, Jaclyn in White Lotus season 3 is another muse, with her opulent kaftans and logo-splattered Gucci hat. Ravello is ready for you.

2. String Bikinis
Style Notes: Barely-there string bikinis have been a dominant silhouette for several summers, but this Copacabana look is sticking around for another year. A black or white triangle bikini is a trusted base to many-a beachwear looks, however for those looking for something a little extra there are plenty of styles with extra embellishment, from beading to chain detailing. The stand-out piece from Frankies Bikinis’ collaboration with Realisation Par is undoubtedly the triangle bikini with cherry crochet detailing on the trims.

3. Floral Touches
Style Notes: Swimwear this year is all about the finer details, and the wider trend for corsage detailing is making its way into your suitcase. Brands such as Maygel Coronel, Marlies Grace and Magda Butrym are leading this look, with swimsuits and bikinis adorned with floral embellishments. Floral appliqué might have once been tarnished by synchronized swimmers’ caps, however in 2025 this is a romantic way to bring something extra to classic suits, without making it look like you’re about to launch into a choreographed routine. But note this is swimwear that is best for lounging, rather than laps.

4. Sporty Trims
Style Notes: This is perhaps the most dominant swimwear trend for 2025, as when compiling the shopping for this feature I noticed that almost every brand has embraced the sporty trim. While premium swimwear brands like Hunza G, Toteme and Gucci are leaning into this varsity aesthetic, it’s also seen across the high street M&S’s lime green iteration is particularly strong. Miu Miu notes that its technical knit swimsuits are inspired by styles from the 1920s, made from a technical yarn, but can also be worn away from the pool as a bodysuit.

5. Hardware
Style Notes: The Kardashian-Jenners are responsible for many-a swimwear trend, and this summer Kylie had a studded moment in Gimaguas’s gunmetal grey triangle top and shorts covered in silver stud detailing. Dial up the attitude with metallic hardware, from chain straps to stud trims to silver rings, which brings a toughness to otherwise simple suits.

6. Earthy Tones
Style Notes: When it comes to colour trends, earthy browns, khakis and rust shades are dominating for summer 2025, and this also applies to swimwear. Hunza G has been a big instigator of this look, with its crinkled suits in neutral shades, while chocolate brown is an elegant alternative to black that looks beautiful with natural fabrics, such as linen sets.

7. Nostalgic Print One Pieces
Style Notes: All ‘90s kids will undoubtedly have family albums filled with pictures of them in printed one pieces, and this year there is an abundance of swimsuits that have this nostalgic sensibility. From Miami-worthy designs covered in vibrant postcard prints to blue and white retro florals, there is something wholesome and spirited about this look. Pair with denim shorts and flip-flops, and your swimsuit can double as a playful holiday top.

8. Polka Dots
Style Notes: Another trend endorsed by Kylie Jenner on her Italian jaunt this year, polka dots are having a moment for summer 2025. There is something very La Dolce Vita about a spotted bikini, and many styles embrace a timeless, retro silhouette, with under-wiring or halterneck straps. Dua Lipa has also had a polka dot moment this summer, wearing a With Jéan spotty string bikini with a lace trim, no doubt further fuelling the trend.
