Blue Swimsuits

A blue swimsuit is one of the most dependable pieces in swimwear - flattering against almost any skin tone, easy to dress up with a sarong or wear plain, and rarely something that dates from season to season. Our blue swimsuit edit brings together designer one-pieces from Seafolly, Vix Swimwear, PQ Swim and Sea Level, spanning soft powder blue through to rich cobalt and navy.

One-pieces have a different job to do than bikinis, and blue tends to suit that job particularly well. Because a swimsuit covers more of the body, colour and cut work together to shape the overall silhouette far more than they do in a two-piece - which is why our blue edit spans such a deliberately wide range of shapes, from minimal cut-out styles to fully supportive, structured designs.

Blue Swimsuit Shapes and Silhouettes

If you want a swimsuit with a bit of extra design detail, our cut out swimsuits collection includes several blue styles with waist or side cut-outs that add shape without sacrificing coverage elsewhere. For a sportier, more secure fit, our high neck swimsuits range carries blue in both plain and printed fabrics, and our one shoulder swimsuits collection offers an asymmetric alternative to a classic straight neckline. If support is your priority, our supportive swimwear range carries structured blue one-pieces built for a fuller cup.

Fit tends to matter more with swimsuits than bikinis, simply because there's more fabric doing more work. Look closely at the back detail on each product page - racerback, cross-back and standard straps all sit differently, and blue swimsuits in particular are available across all three depending on the brand.

Blue Swimsuit Styles Worth Knowing

Navy and cobalt block-colour swimsuits remain a consistent best-seller each season, largely because they work as hard for lap-swimming as they do for sunbathing. If you'd rather have some pattern, blue geometric and wave prints from Seafolly and PQ Swim bring texture and movement to the silhouette without losing the flattering quality of the colour. Our bandeau swimsuits collection also carries a handful of strapless blue styles, for anyone who wants a one-piece without conventional shoulder straps.

Beachwear to Pair With a Blue Swimsuit

A blue swimsuit is one of the easiest pieces to build a full look around. Our wider beachwear collection includes plenty of neutral cover-ups, sarongs and kaftans that let a strong blue take the lead rather than compete with a busier print elsewhere.

Fabric and Fit Notes

Most of our blue swimsuits use chlorine-resistant Lycra or nylon-elastane blends designed for regular swimming rather than sunbathing alone. Darker navy tones hold their colour particularly well over a season, while brighter cobalt and cornflower shades benefit from a cold rinse after chlorine or saltwater exposure to help preserve vibrancy.

Ways to Style Your Blue Swimsuit

Beach holiday: A powder blue swimsuit under a white kaftan is a reliably elegant, low-effort combination.

Poolside at a resort: Navy and cobalt tones pair particularly well with gold jewellery and a structured beach bag.

Active swimming: A high-neck or cut-out blue swimsuit in a supportive fit holds up well through repeated laps, without sacrificing on style.

Accessorising: Silver and white accessories tend to complement cooler navy tones, while gold works better with warmer cornflower and sapphire shades.

Frequently Asked Questions

What's the most flattering blue for a one-piece swimsuit? Deep navy and cobalt tend to be the most universally flattering, offering good contrast and a slimming effect across most skin tones, though lighter powder blue works beautifully for anyone who tans easily.

Do you have blue swimsuits designed for lap swimming? Yes - our high neck and supportive swimwear ranges include several blue styles built with more structured, chlorine-resistant fabric specifically for regular swimming.
