Whether you’re eyeing cozy knits, tailored corpcore pieces, wedding guest attire, summery prints, or timeless, high-quality purses and shoes that will last in your wardrobe for years to come, Reformation has long been a destination for chic, versatile wardrobe staples. Now, the brand is expanding its presence in sustainable fashion with the debut of its first seasonal swim collection of 2025. After reintroducing swimwear as a category last year for the first time since 2019, the brand is back with more eco-conscious designs inspired by its best-selling pieces.

The latest Ref Swim line, which launched yesterday, is made from EVO by Fulgar, a renewable, super-soft biobased fiber that contains no plastic and is derived from the castor plant, which requires minimal water to grow. The collection offers a variety of silhouettes, from barely-there bikinis to sporty one-pieces, with vintage details that align with Reformation’s signature aesthetic. Popular looks like the Joy ($148) and Rio which were fan favorites last year, are also making a comeback.

Designed to fit seamlessly into an existing Reformation wardrobe, the collection is both practical and stylish—perfect for spring getaways and sophisticated summer beach days. The line ranges in sizes from XS to XL and each look pairs perfectly with a chic crochet head scarf ($98), platform sandals ($148) or a tote ($298) for your essentials.
