The best colourful bikinis for curvy women in the UK (2026)

The UK swimwear market has a problem. Walk into any high street store and the plus-size rail looks exactly the same as it did ten years ago — navy, black, and the occasional reluctant pattern. We started Orixah because we were done with it.

There is a persistent, unspoken message in how most brands approach plus-size swimwear: cover up, blend in, take up less visual space. The cuts are designed to minimise. The colours are chosen to disappear. The prints, when they exist at all, are small and cautious.

We think that is wrong. Not just aesthetically — philosophically wrong. A size 16 body deserves the same terracotta tropical print, the same bold graphic stripe, the same luxurious fabric as any other body. That is not a radical idea. It should be the baseline.

So here is our honest guide to finding genuinely beautiful, colourful swimwear as a curvy woman in the UK in 2026 — what to look for, what to avoid, and why quality matters more than you might think.

What most plus-size swimwear gets wrong

Before we talk about what to look for, it is worth naming the specific failures you have probably already experienced:

• Fabric that doesn't hold its shape. Cheap stretch fabric sags after a few wears, loses its structure in the water, and stops supporting you exactly when you need it most.
• Colours that fade fast. Mass-market swimwear uses dye processes that are not designed for salt water and chlorine. That vibrant print you loved in the shop is three shades duller by the end of the holiday.
• Cuts designed to conceal, not celebrate. There is a difference between a swimsuit that flatters a body and one that hides it. One makes you feel beautiful. The other makes you feel like you are getting away with something.
• The wrong size range. "Plus size" at many UK brands ends at a size 18. The range is tokenistic, the fit is inconsistent, and the styling options are a fraction of what smaller sizes get.

What actually works — what to look for

Double-lined fabric

This is non-negotiable for plus-size swimwear. Double-lining means the fabric holds its shape, stays opaque when wet, and keeps its structure across a full day of wearing. Single-layer swimwear goes thin and saggy in the water. Double-lined fabric does not. This is one of the reasons every Orixah piece is double-lined — it is a quality standard, not a luxury add-on.

Bold, saturated prints

Colour works on every body. In fact, a well-placed bold print draws the eye with intention — it is far more flattering than a nervous small pattern trying not to be noticed. Tropical prints, geometric stripes, and graphic designs all look extraordinary on curves. The key is confidence in the print — not a print that looks like it is apologising for being there.

Adjustable straps and proper support

For larger busts especially, the strap and cup construction matters enormously. Look for wide, fully adjustable straps, underwiring where needed, and cups that are structured rather than just fabric folded over. A bikini top that does not support you is not a bikini top — it is a prop.

Brazilian cut bottoms

The Brazilian approach to swimwear has always understood the curvy body differently from European and American conventions. Brazilian cuts tend to sit higher on the hip, cut the leg in a way that elongates, and provide real coverage at the back without excess fabric. It is not about showing more — it is about cutting the fabric in a way that works with the body rather than against it.

Why we made Orixah inclusive from day one

When Petra founded Orixah, the brief she gave herself was simple: make the swimwear she had been looking for and could never find. That meant bold prints that did not flinch. That meant fabric that lasted. And it meant sizing that actually included the women the brand was designed for.

The Orixah woman is not defined by her size. She is defined by her energy — the confidence, the love of colour, the refusal to make herself smaller than she is. She exists at every size. And she deserves swimwear that matches that energy.

Every piece in our collection is available in inclusive sizing, made from premium double-lined fabric handmade in Brazil, and designed to look as extraordinary on a size 18 as on any other size. Because it should.

How to style bold swimwear as a curvy woman

A few things that genuinely help:

• Match your cover-up to the print's palette, not the exact print. A terracotta bikini with a rust or burnt orange kaftan looks intentional and beautiful. Matching exactly can overwhelm.
• Wear the boldest thing you own first. Put it on before you think about it. The hesitation never helps and usually lies to you about what looks good.
• Invest in one great bikini rather than three average ones. The right piece at the right quality changes how you feel on the beach. The economics of buying better are in your favour — one piece that lasts four summers costs less than four pieces that last one each.
