Plus Size Swimwear in the UK: Finding What Works for You
Shopping for swimwear can be one of fashion's more daunting experiences — but it doesn't have to be. The swimwear market for plus size and curvy women in the UK has expanded significantly in recent years, with more flattering cuts, supportive constructions, and confident designs than ever before. Whether you're heading to the coast, a poolside holiday, or an outdoor lido, here's how to find swimwear that makes you feel genuinely great.
What Are the Most Flattering Plus Size Swimwear Styles?
- Ruched swimsuits: Ruching across the midsection is one of the most effective design tricks in plus size swimwear — it creates texture that breaks up the mid-section visually. A ruched one-piece or two-piece is almost universally flattering for curvy figures.
- Underwired swimwear: For larger busts, underwired cups provide genuine support and shape throughout the day — not just coverage. Look for adjustable straps and a broader back band that distributes weight evenly.
- High-waisted bikini bottoms: One of the most popular choices for curvy and plus size women, high-waisted bikini bottoms offer coverage and structure around the midsection while showing off the legs. The effect is similar to high-waisted denim — elongating and flattering.
- Wrap-style swimsuits: A swimsuit with a built-in wrap or tie detail at the front creates a defined waist on any figure. Paired with a beach kaftan for walking around, this is both practical and stylish.
- Tankini: A two-piece with a longer top that covers the midsection. Popular among plus size women who want more coverage than a bikini without the sensation of a one-piece.
What to Look for When Buying Plus Size Swimwear
Fabric quality and stretch: Look for nylon/lycra blends that retain their shape after swimming. Cheaper fabrics lose elasticity quickly and can become see-through when wet.
Bust support: For DD+ cups, look specifically for styles with underwire, adjustable straps, and a broader band across the back. Halter neck tops also offer excellent support for larger busts by distributing weight through the neck tie.
Length and rise of bottoms: Higher-rise bikini bottoms provide more coverage and support for the lower abdomen. Wider-banded styles are more comfortable and more secure than string ties for active swimming.
Colour and Pattern Tips
Bold, vibrant colours and confident prints look exceptional on curvy figures — there's no rule that says you need to stick to black or dark tones. Vertical stripes are elongating; horizontal stripes are a bolder choice but work beautifully with confidence. Contrasting colour at the waist — a darker centre panel — can create the illusion of a more defined waist in one-piece styles.
Styling Your Swimwear
A beautiful coverup transforms your beach or pool look. A longline kaftan in a complementary print, a lightweight linen shirt, or a sarong tied at the hip are classic options. Wide-brimmed hats, quality sunglasses, and a canvas tote complete the look. Flat sandals or espadrilles are both practical and stylish for beach settings.

Frequently Asked Questions: Plus Size Swimwear UK
What is the most flattering swimsuit for a curvy figure?
A ruched one-piece or a high-waisted bikini with a ruched or structured top are the most consistently flattering choices for curvy figures. The ruching creates visual texture that draws attention away from the midsection, while the high waist provides support and creates a defined waistline. For larger busts, an underwired bikini top with adjustable straps and a fuller cup is essential — both for support and for a flattering silhouette.
What swimwear provides the most support for a large bust?
Underwired bikini tops or underwired one-piece swimsuits provide the most support for larger busts (DD+ cups). Look for adjustable halter-neck or wide shoulder straps, a firm underbust band, and fully moulded or foam-lined cups. Avoid triangle-cup bikinis and unstructured bandeau tops, which provide minimal support for larger cup sizes. Specialist swimwear brands with dedicated cup-sizing (rather than S/M/L) will give the most accurate fit.
Should plus size women wear one-piece or bikini swimwear?
Both work well — it's entirely a matter of personal preference and confidence. A one-piece swimsuit in a wrap or ruched style creates a smooth, elongated silhouette. A high-waist bikini is an equally flattering choice and allows more flexibility (mix and match tops and bottoms to get the best fit for your proportions). Many plus size women find they need a different size for their top half than their bottom half, which makes bikini separates a practical advantage.
What coverup should you wear with plus size swimwear?
A longline kaftan is the most flattering plus size beach coverup — it provides coverage without clinging, moves beautifully in the breeze, and looks stylish in a print or solid colour. A lightweight oversized linen shirt is a versatile alternative that doubles as a casual summer top away from the beach. Sarongs tied at the hip are a classic option that shows off the legs while providing coverage around the midsection.
Where can you find the best plus size swimwear in the UK?
UK swimwear shopping has expanded enormously in recent years, with many high street and online retailers now offering dedicated plus size ranges up to a size 28 or 30. When shopping online, look for brands that offer detailed size guides, cup-size options for bikini tops, and customer photos that show the swimwear on a range of body types. This gives the most realistic picture of fit and appearance before purchasing.
