Real Reformation fans will remember the brand’s first foray into swimwear back in 2019, but if you thought that small drop was good, prepare to be amazed by the full-fledged collection that arrived at both Ref and Shopbop this week. This time around, in addition to a larger selection of more elevated swimsuit styles—including both bikinis and maillots—the new swim curation at Reformation is a step further when it comes to sustainability.

Originally, the brand had made its swimwear out of ECONYL, regenerated nylon made out of trash. But according to a press release, it wasn’t sustainable enough for Reformation. So with this second chance, they’ve introduced a new, non-synthetic fabric called EVO by Fulgar, which is a renewable bio-based fiber that they used in conjunction with ECONYL leftovers in order to combat waste.
