SKIP TO: Shop the best swimwear brands 2025 | How we chose the best swimwear brands.
1. Free People
Free People's swimwear offering is always great, but for SS25? They've really outdone themselves. Think: styles cut with flatteringly high legs, innovative fabrics (including towelling and terry) and romantically printed two-piece bikini sets.
2. Lounge Underwear
Not just one of the best lingerie brands, Lounge Underwear is also a top contender for swimwear. Catering to proper bra sizes for the perfect fit, each Lounge Swim piece is sold separately to allow you to pick your own colour story to debut poolside. They have underwired, wire-free and padded cups, as well as bikini and thong bikini bottoms.
3. Hunza G
Founded back in the 80s, Hunza G shot to fame when they launched that cutout mini dress Julia Roberts stepped out in in Pretty Woman. 30 years later, it was relaunched under the creative direction of Georgiana Huddart, with high-waisted bikinis and bathing suits the stars of the show: all cut from the same figure-sculpting seersucker fabric.
Their styles – which claim to fit all body types (one-size-fits-all) thanks to the aforementioned signature and stretchy crinkle fabric they're crafted from – are available in a plethora of bright colours and simple silhouettes. Think: scoop necklines, spaghetti straps and, on occasion, one-shoulder silhouettes. So chic and flattering, in fact, that almost every high street label has followed suit. Luxury swimwear doesn't get much better than this; there's a reason Hunza G comes Chrissy Teigen and Rita Ora approved.

This summer, the sell-out swimwear collection that is SKIMS SWIM is back and arguably better than ever thanks to an impeccable size range. SKIMS Swim has been one of SKIMS most explosive categories since their launch, with over 500k all time waitlist signups for SKIMS swim and thousands of 5-star reviews on various styles.
6. H&M
It goes without saying: H&M swimwear is really good if you don't want to spend a bomb (but would quite like to appear as though you absolutely have). While their styles may not last for quite as many summers as something from a designer swimwear brand would, they will make you feel a million dollars. And everything is bang on trend. This season, you'll find us in their metal-detail bikini and ruffle-trim tummy control swimsuit.

From the best jeans to blazers, white shirts and knitwear, Topshop is our go-to for basically everything we could ever need. Including swimwear. Their latest tie-dye prints have been sat on our wishlist since they were added to the ‘new-in’ section of ASOS, and we love that they cater to plus size swimwear too.
17. Norma Kamali
Norma Kamali has more than half a century worth of experience in the fashion industry, and her swimwear range mirrors the neon hues and playful prints that we've come to adore in her main ready-to-wear collections. Their bestseller? That'd be the Mio swimsuit: a favourite among brides-to-be in the all-white hue.
18. Frankies Bikinis
Loved by Hailey Bieber and Gigi Hadid, Frankies Bikinis is a Californian swimwear brand that champions colour, Y2K-inspired pattern and playful silhouettes. Make a beeline for all the Malibu-cool vibes, crochet styles, and that ‘Gemma One Piece’ in 'pink punch' (which sold out instantly in 2022 after it was worn by Cassie in Euphoria, before racking-up a 500-person waitlist. No biggie).
19. Cover Swim
For all of your modest swimwear needs, make a beeline for Cover Swim. Founded by Lisa Moora, every style in the line is designed to protect skin from the sun. They provide UPF 50+ protection to block 98% of harmful UV rays, and the fabrics are both breathable and quick-drying. Epic.
