It may come as no surprise that Reformation’s swimwear comes with new and improved materials. The line, which retails from $68 to $168 in sizes XS-XL, is made from a renewable and bio-based fiber called EVO by Fulgar. And, according to Reformation’s chief innovation officer Alison Melville, the product will only grow more sustainable with each seasonal drop (check out their most recent drop here!). The first range incorporated deadstock fabric from the brand’s debut swimwear collection in 2019, and Reformation promises to “continue innovating and trying out new materials until we create the most sustainable swimwear possible,” according to Melville.
Instantly attracted to the striking bikinis and one-pieces, PS editors were eager to get our hands on the swimwear designs, many of which were influenced by bestselling products across other categories. “We designed Ref Swim to complement and round out our customers’ existing Ref wardrobes,” Melville tells PS. “Throughout the design process, we were inspired by the concept of outfitting and looked to the silhouettes of some of our top performing apparel items to create complementary swim pieces.” For example, the Bryson Dress is one of their most popular styles in 2025 so they carried the vibrant red color and the sweetheart neckline detail through in the Soleil Bikini Top.
Melville confirms that the success of the drops has exceeded expectations, with solid colors being most popular — a trend that speaks to the Ref shopper’s love for ’90s minimalism. The Tossa Top (now out of stock), Azure Bottom, and Soleil Top were within the top five SKUs at the original time of publishing this story, and they just so happen to be three of the pieces we selected to try at PS.
Ahead, you’ll hear from four different editors about their experiences trying Reformation swimwear with one shared sentiment: the quality is in the fabric and the fit. Plus, we’ve added a couple more styles for you to shop from.
