9 swimsuit brands you need to know this summer - from H&M to Hunza G and Heidi Klein

The best swimsuit brands will make you look and feel amazing. Whether you’re after a sleek one-piece or a confidence-boosting bikini, these are the labels to look out for. They all create swimwear that will fit and flatter your shape, whatever your size, style or budget.

Shopping for the best swimsuit brands can feel overwhelming. Much like hunting down the best bras, swimwear shopping is no mean feat with many things to consider, such as aesthetics, cut and fabric. The best swimsuit brands will nod to the swimwear trends 2025, but generally, swimwear doesn’t change as much as clothing year-on-year, so choose wisely and you’re likely to wear your swimsuit from one summer to the next.

As swimwear can feel exposing, start by choosing a silhouette that you feel most comfortable in, whether that’s a bandeau bikini for topping up your tan or a sporty one-piece for nailing your pool laps. Fabric is also key, so you’ll want to look for supportive materials that hold you in, such as spandex and synthetic fabrics that will hold their shape through multiple washes and wears. Remember, swimwear often expands when wet, so you’ll want to ensure a snug fit.

9 BEST SWIMSUIT BRANDS TO SHOP IN 2025

“The important thing to consider when shopping for a swimsuit is what you actually intend to do in it! If you plan to swim for exercise, it’s wise to invest in a supportive sporty style that will allow you to be active. Opt for brands that use chlorine-resistant fabrics and designs that are cut more generously to allow for movement. There are some great suits with sleeves that will protect you from the sun, ideal for surfing or paddleboarding,” says fashion editor Julie Player.

“If you plan to lie back and relax, with the odd dip in the pool to cool off, you can go for something less practical. The ideal design will make you feel confident and flatter your figure. A wrap-front swimsuit that accentuates the waist is universally flattering on all figure types, and look out for tummy control panels and hidden underwired cups for extra support.”

If you’re dreaming of a beach getaway or are lucky enough to have one already in the calendar, we’ve curated an edit of the very best swimsuit brands to add to your summer capsule wardrobe.

Because we only want to bring you styles we genuinely recommend, our fashion team (and some friends!) have roadtested several of the brands ourselves. Enjoy!

1. Boden

One of the best British clothing brands, Boden was dreamt up by founder Johnnie Boden from his kitchen table back in 1991. The clothing line is big on colour and print and its swimwear range is no different. Covering everything from mix and match bikinis, tankinis and swimsuits, expect playful pieces in classic shapes that are designed to fit and flatter.

Considered details such as clever panelling and body sculpting lining give it the extra edge and we love the wide range of prints that perfectly coordinate seamlessly with each other. There’s no chance of finding a style you don’t like here and all its nylon and polyester swimwear fabrics are made from recycled materials too.

2. Next

Next has always nailed it when it comes to clothing, so it’s no wonder the swimwear collection is top notch too. Affordable and stylish, with its extensive range, you can stick to a timeless black one-piece or lean into one of the hottest trends of the summer.

Next offers some really impressive tummy control technology, helping to smooth and sculpt your shape so you feel confident from every angle. Perfect for stocking up on all the essentials for your summer vacay, why not add one of their chic cover-ups to your basket too?

3. Panache

This lingerie expert brand is pretty clued up on what makes a good fit so expect plenty of support, lift and considered details such as tummy control and removable straps. Catering to the D+ market, the range doesn’t skimp on style either with their latest collection taking inspo from the Mediterranean with nautical prints, monochrome hues and scallop hems. There’s swimsuit types for everyone including tankinis, long-sleeves, plunge and balcony necklines. Much of the fabric has a high chlorine resistance too making them durable and lasting from one summer to the next.

4. Pour Moi

According to the website, "Pour Moi started in a tiny office above a shop in Macclesfield, packed with materials, cardboard boxes, two staff members and one belief - that people shouldn’t have to overpay for good-fitting lingerie, no matter what their size."

Skip forward twenty years, and now Salma Hayek is the brand's biggest fan!

5. Bravissimo

If you're blessed with bigger boobs, Bravissimo has got you covered. They're one of the best brands in the business when it comes to bras for larger busts, so it follows that their swimwear is just as good.

They cater for cup sizes D and above, offering both wired and non-wired styles, as well as tummy control swimsuits as well as mix and match bikini options.

6. Hunza G

One of the best swimsuit brands right now, Hunza G’s USP is its sizing. Available in one size only, the brand's signature crinkle fabric expands and contracts to fit sizes 6-16. Sticking to a number of classic styles that get repeated year-on-year, the brand introduces more timely aesthetics by concentrating on the latest colour trends or small design tweaks to accommodate new necklines or hardware. They also have a maternity range and a kids range, so you can coordinate with your mini me.

While the brand only recently became a household name, Hunza G has been around since 1984 and was responsible for the iconic cut-out mini dress worn by Julia Roberts in Pretty Woman.

7. H&M

Need to replace your faded old swimwear on a shoestring budget? Head to H&M. Almost everything in its swimwear collection comes in at under £35 for a one-piece or set, making it the most affordable swimwear brand in our round-up.

But just because it stocks some of the most affordable swimwear, it doesn't mean they won't last, and these fabrics are good enough to stand the test of chlorine and saltwater. Just make sure you care for them properly, which means rinsing them with water when you get home from the pool or the beach and washing them according to the instructions on the garment label.

8. Sea Level

With a country full of stunning sandy beaches and endless sunshine, you can always rely on the Australians to do swimwear well, and Sea Level is no exception.

Born in 2018, the now well-established Australian swimwear brand embraces the Aussie lifestyle with a swim collection that offers "high-precision contoured swimsuits" for women, whether they’re catching some waves or relaxing by the pool.

Sustainability is a huge focus for the brand. 90% of the collections are made from recycled base cloths, and according to the website, "To achieve a 100% recycled garment, our team is working towards incorporating recycled linings, performance mesh and trims. Our fabric technology is industry-leading: Swim Level collections are made using a revolutionary regenerated nylon filament yarn derived from pre-consumer waste."

9. Heidi Klein

Heidi Klein swimwear doesn’t come cheap, but it’s almost impossible not to covet. Loved by Pippa Middleton, this is a designer swimwear brand that exudes timeless luxury. The British brand has impeccable attention to detail, and also has a beautiful ready-to-wear collection. The bags, hats and sarongs are beautiful too. It's a one-stop holiday shop!

FAQs

Where are the best places to buy swimsuits?

The best places to buy swimsuits will depend on a few different factors. First up, budget. You don’t need to spend a fortune to find swimwear you’ll feel confident in, with affordable swimwear options from the likes of H&M leading the way. If money is no option, then treat yourself to something a little fancier from brands like Melissa Odabash or Heidi Klein.

Secondly, consider that sustainability is a big deal in swimwear too, as the kind of stretchy fabrics that best suit this kind of clothing are also, by their nature synthetic, which isn’t always great for the planet. However, the best swimwear brands are making conscious moves to a more sustainable future, with many brands opting for recycled fabrics and new technological fabrics with low carbon footprints. In addition to this, many designer swimwear brands opt for small batches or on-demand production, minimising long-term waste.

And finally, just like shopping for the best bras or best shapewear, your clothing size will be a consideration as to where is best to buy swimwear too. If you're plus size or have a fuller bust, look to lingerie or plus size specialists as these labels will have the best support and cuts for your frame.

Where are the best places to buy luxury swimwear brands? 

Where you shop for luxury swimwear will depend on the kind of look you’re going for, as well as your commitment to quality and sustainability. Our top picks for the best places to buy luxury swimwear include Hunza G and Heidi Klein. You can shop directly from the websites, or via retail partners, just make sure you've fully read the returns policies before ordering.

When buying luxury swimsuits, consider the longevity of the item and the quality of the fabric. “There are multiple things that set it apart from the high street,” explains Georgiana Huddart, Co-Founder and Creative Director at Hunza G. “Number one is the production of it, how and where its produced, in what quantities and with what techniques. I would say most swimwear companies that are considered designer also have a clear aesthetic which means they are doing their one thing and doing it super well," she says. "For example, Hunza G is based around one fabric and we know this fabric inside out. We have perfected it, worked on it, improved it, and tested it", ensuring that the Hunza G crinkle delivers on form and function.
