Best plus-size swimwear: stylish swimsuits, bikinis and tankinis

Shopping for plus-size swimwear doesn’t have to be a headache. Whether you're jetting off on holiday or just taking a dip at the local pool, we've found the very best swimsuits, tankinis and bikinis you can buy today.

There’s a bit of an art to getting plus-size swimwear right. Just like any swimwear it has to perform well, stand up to chlorine and salt water and suit your personal style. But plus-size swimwear also needs to support your curves so you can switch off and relax on the beach. No one wants to worry about a boob popping out or feeling uncomfortable because your swimsuit is cutting into your thighs. 

We’ve hunted high and low to find the plus-size swimwear that will support you, fit your body and bring you joy with a range of colours, prints and styles. From swimming costumes to bikinis and tankinis, there’s a perfect swimwear option out there for everyone. 

Gone are the days when being plus-size meant hiding out in a black one-piece. Why not make this the summer you embrace a bright colour or a bold print? 

Here is the best plus-size swimwear to buy in 2022.

1. Best overall plus-size swimsuit: CUPSHE V-Neck Ruffle Mesh Swimsuit

If you’re looking for a swimsuit you feel confident in that adds a little flair to your summer look, this is the one. 

We love the mesh panel which is cleverly placed to highlight your waist. The ruffle arms are a fun, playful detail without feeling too much for the local pool.

This [Derssity swimsuit] was surprisingly flattering when I needed to quickly lay my hands on a costume recently. I was worried it would be a bit old fashioned but the colour seems to lift it (I got purple) and the ruching isn’t too much.” (Tried and tested by Mumsnet user 1frenchfoodie)

This Derssity Tummy Control Swimsuit comes in a huge range of colours so you can find the perfect style for you. 

We love the dark purple shade which is simple enough for the local pool but wouldn’t look out of place in a luxury resort either. This one-piece has been made to help flatter your tummy with ruched fabric all across the middle. 

The plunging V-neckline and supportive straps are brilliant for fuller busts and the cross back, adjustable straps mean you can find the perfect fit.

“I bought a couple of Boden swimsuits last year and am really happy with them - they are simple but very flattering and excellent quality.”  (Tried and tested by Mumsnet user WrenDouglas)

Boden swimsuits have a great reputation and we can see why. The British brand is known for its high-quality construction, but it’s also known for stylish design. 

We love this colourful, patterned swimsuit. It's simple and elegant and will look classy for years to come. The fabric is thick enough to mean you feel confidently covered and it features body sculpting support too.

The plunge neckline will add subtle sexiness with a hint of cleavage, plus the cups are slightly padded to achieve a smooth silhouette. We're also impressed with the contrasting band under the bust which will accentuate an hourglass figure.

plus size swimwear

This sporty plus-size swimming costume by Delmira is perfect for those of you who head to the pool regularly. 

This zip-front design with contrast edging has a fun, retro look to it and we love that the zip will make it easier to peel this costume off after an energetic dip. 

Built in soft cups will provide gentle support and some ruching across the middle will help to flatter your stomach. There's also 15 colourways and patterns to choose between so you can find one to suit your style.

Pros

  • Soft cup support
  • Affordable price point

11. Best swimsuit dress: Miraclesuit Miracle Dress Women's Aurora

Miracledress

Price: £215 | Buy now from Miraclesuit

“I have a couple of Miraclesuits. Worth every penny.” (Tried and tested by Mumsnet user professionalnomad)

“Miraclesuit is excellent for tummy control, the suits are flattering and good quality.” (Recommended by Mumsnet user merrymelody)

If it usually takes a little pep talk from yourself to head out in a swimsuit (we’ve all been there!), a Miraclesuit is the perfect choice. And, while it certainly doesn't come cheap, Mumsnet users have a lot of praise for this brand.

Miraclesuit swimming costumes and dresses prioritise tummy control in their design. They’re made to minimise the stomach area and hopefully boost your confidence in the process. 

While we don’t think anyone needs to minimise anything in order to plunge in while on holiday, we do love how this Miracle Dress has incorporated a waist-cinching design and flared-out skirt into this costume, creating a lovely hourglass shape.

Pros

  • Tummy flattering design
  • High quality

Cons

  • Investment price tag

Key specs

  • Size range: 16W to 24W (US sizing)

“Snag now do swimwear.” (Brand suggested by Mumsnet user JackieWeaversZoomAc)

Snag Tights are true champions of plus-size bodies, so the arrival of their swimwear range was a day for celebration. 

This animal print halter neck design is gorgeous and playful; its contrasting prints will boost your confidence as you get ready for a dip. Or, if you fancy something a little more subtle, then there’s also a gorgeous teal suit we’ve got our eye on. 

The swimming costume is also lined with the brands’ signature ‘power mesh’, a clever lining that means you feel supported. 

Pros

  • Power mesh lining
  • Animal print design

This versatile black one-piece can be worn in multiple ways with its adjustable straps. Either style it as a swimsuit with capped sleeves, or transform the sleeves into straps, a halter neck or a cross back.

The adjustable neckline not only means you can wear this swimsuit on repeat, changing how you style it every day, but it also means you can choose how much or how little you show, ensuring you feel confident by the pool.
