Green is one of those swimsuit colours that actually does something. It works against a tan, it photographs brilliantly in natural light, and it has a richness that black and navy simply cannot match. We’ve been particularly focused on green this season, and not just the colour but what the swimsuits actually do once you’re in the water. Because that is where most swimwear quietly fails. Cups that lose their shape, straps that stretch out after one swim, fabric that goes thin and strange after contact with chlorine or salt. We’ve been strict about this edit. Every swimsuit here holds its structure, keeps its colour, and fits the same way coming out of the pool as it did going in. We’ve pulled together one pieces and bikinis across shades from deep forest to bright emerald to softer sage, because green has real range and each shade has its own argument. These are the swimsuits worth actually swimming in rather than just wearing poolside and hoping for the best. Looking good in the water is a different and more demanding standard, and these meet it.
