Aqua Green's newest line of swimsuits, called Eco Swim, debuted this summer. Pennsylvania-based and now in its fourth generation, the company regularly engages in waterway cleanups and has the goal of becoming "the most sustainable swimwear manufacturer on the planet." A combination of recycled polyester and nylon, there are plenty of full-coverage maillots as well as simple but elegant black and taupe bikinis like the one here. ($54-$58 per piece at everythingbutwater.com, or at select boutiques in Florida, New York, Indiana and Canada)
