Best Sustainable Swimwear that Gives Back: Vitamin A Made from a plant-based polyamide sources from castor beans, Vitamin A is making huge strides within the eco-friendly fabric space. Of course, all garments come in biodegradable packing, and we just can't get enough of this gorgeous green Moss Bralet Top (£133) and Emmie Bottom (£138). And through a partnership with 1% For The Planet, the brand gives back a portion from every sale to organisations that protect our oceans. Another win.
