Navy is the one swimwear colour that never needs justifying. It works on every skin tone, photographs beautifully in bright light, and doesn’t show the wear that white does after a day in the sun and salt water. We’ve always had a soft spot for a navy bikini specifically because it manages to look both effortless and put together at the same time, which is a harder combination to achieve than it sounds. This edit brings together the navy bikinis we’d genuinely pack ourselves. Some are classic triangle styles with that clean, timeless silhouette. Others have more structure, underwire, thicker straps, real support for people who actually swim rather than just pose at the water’s edge. We’ve included options across price points because a good navy bikini doesn’t have to cost a fortune, it just has to fit properly and hold its shape after repeated wear. The navy ones always do the heavy lifting on holiday and somehow still look sharp on the last day as the first. Pack one and you’ll understand exactly why we keep coming back to this colour.
