10 Best Plus-Size Swimwear UK 2023 | Simply Be, ASOS Curve and More

Simple Be have really created a summery sizzler with this bandeau bikini set and we love the removable sleeves that allow you to adapt the top to suit your mood. Vibrant greens, pinks, and reds come together in this all-over tropical fruity print to get you in holiday mode wherever you are.

Being specialists in plus-size women's clothing, you can feel safe in the knowledge that you'll not only look great but the fit will feel fabulous too. The whole bikini set is stretchy including subtly elasticated briefs giving the waist a delightful pulled in effect – one of the many reasons it's our numero uno choice.

Nothing says seaside like white and blue polka dots and ASOS DESIGN's Frill Plunge costume is bringing all the right vibes. Part of the brand's responsible edit, this swimsuit is made from recycled polyester for a more eco-friendly choice.

With a plunge neck and brief cut, the design of this piece is on point but it's certainly the gorgeous frill trim that brings the whole thing together in a delightfully feminine way. We're just dotty for this fit.

There are tons of fancy options out there that have frills and detailing, but this affordable costume by Delimira keeps things simple. Made in a retro style, it features tummy control and a U-shape back design that is reminiscent of '50s swimwear styles.

We think this is ideal for those who prefer a modest look or want a simple one-piece to add to a collection of different kinds of swimwear for different moods. It is also made from a comfy, quick-drying fabric and is not only available in a lovely range of colours but in sizes up to a UK 30 too. 

Many of the swimwear pieces on ASOS are sold by themselves to allow you to mix 'n' match to create your own customised look. These ribbed shorts by We Are We Wear really stood out to us, firstly because they're a poppin' neon green but also because they make a statement while being super comfy!

Not everyone feels confident enough to rock tiny bikini bottoms or a high-cut swimsuit, and that's totally fine because these thigh-cut shorts create a sassy look all of their own and can be paired with almost anything beachy.

Our prediction is that brown is going to be a major colour this year, and the humble polka dot is very on-trend – so why not get ahead with this top by River Island? The knot front, adjustable straps and padded cups make for a cute and comfortable bikini top with a hint of sixties flair.

The fabric blend gives the right amount of stretch and the polka dots look pretty at the beach. Just like many of ASOS's options, the bottoms can be bought separately or you can mix 'n' match. Get ready to embrace rust, umber and chocolatey browns in your repertoire, because they really do look sweet all year round.

We're spoiled for choice when it comes to little black swimsuits, but this one by Missguided is our favourite of the bunch. The twist belt detail adds a dash of elegant luxury that makes this one feel a little more special than the usual black cossie. 

There are other fabulous things about this suit too though, such as the stylish scoop neck, U-shape back design, and the slightly higher brief cut. It's also surprisingly supportive and makes a good choice for a larger bust, too.

If a teeny weeny bikini is your thing and you love an '80s style fruity print, it doesn't come much cuter than this recycled bikini set by COLLUSION. As well as its nostalgic appeal, it's made with recycled polyester for a more sustainable and future-forward choice.

Featuring a halterneck style top with triangle cups and a tie fastening, the Brazilian-cut bottoms really bring the '80s beach vibe with a combo of low-rise and high-cut design. Not for everyone, but all in all, a totally rad bikini set.

Choosing to mix things up a bit, your back will be the star of the show (or the pool) with this piece. The design features an open back with an oversized tie for a unique and rather flirty look.

Made from soft and stretchy swim fabric, the khaki shade works well on every skin tone. It is high cut all the way around the legs and bum which might not appeal to some, but on the upside, it is an ideal choice if you like a high neck – something that can be hard to find on a swimsuit. 

There are plenty of swimwear options in bold, block colours at the moment, but that doesn't mean neutrals aren't also still current, and this bikini from ASOS DESIGN proves that. With a pattern that's reminiscent of a dalmation's coat, it'll look seriously chic poolside.

As well as being made from recycled polyester, it also has some cool details like a twist wrap front, wide straps and a combination of high-waisted briefs and a top with a little more coverage. Our only gripe is that the briefs are cut high which can make your bottom half feel a little exposed, but dependent on body shape, this might not affect everyone.

Tankinis are often a little harder to come across than other types of swimwear but this one from Viottiset is available in a wide range of colours and even more than one style. The ruched top and cut-out bottoms really flatter those curves and look great on the beach.

Although we enjoy the design of this tankini, the size chart ranges from L-4XL instead of the usual UK women's sizing, which isn't only confusing but also a little stigmatising. Some ladies will be perfectly familiar with this sizing though, in which case, don't let us stop you!
