Most swimwear is made of virgin nylon and polyester. We don’t need #PlasticFreeJuly to know that means tons of synthetic, petroleum-derived fibres that won’t biodegrade. Instead, pick from this list of drop- dead gorgeous ethical and sustainable swimwear. Most use recycled plastic from discarded fishing nets – which, according to a study in Scientific Reports, makes up 46 per cent of plastics found in the Great Pacific Garbage Patch – but some use revolutionary fibres such as hemp and, yes, velvet. (We recommend using the Guppyfriend Washing Bag to reduce release of microfibres into the water systems)
