Working around three core principals — conscious making, circular material, and a clean ocean tax — Medina puts sustainable considerations at the heart of its operation. Made primarily from regenerated nylon, the Seaquest Swimsuit in Olive (£321.99) is certainly a standout piece, sitting between bondage babe and beachwear chic. Again, it does have to ship from Europe, so be sure to check any duties and taxes before buying.
