Vitamin A first made waves on the SoCal scene in 2000, debuting with just four perfectly cut black bikinis. But what bikinis they were: Designer Amahlia Stevens’ innovative fit concept—now a staple in the contemporary swimwear market—was dubbed the “California Cut,” a sexy style that forged a thoroughly modern marriage between the super-skimpy Brazilian and the uber-conservative American cut.

Now, a decade later, Vitamin A is still revolutionizing fit while seamlessly blending a laid-back West Coast aesthetic with European high-fashion influences.  It features three distinct—yet complementary—lines of swim and resort wear: the original Vitamin A®Gold Collection, the ultra-luxe Vitamin A®Signature Collection, and the hip, affordable Vitamin A®Silver Collection. All feature Vitamin A’s signature lush color palette, unique hardware details, and rich Italian fabrics.

It’s no wonder, then, that Vitamin A counts Scarlett Johansson, Sienna Miller, Jessica Alba, Kate Hudson and Cameron Diaz among its celebrity devotees. The label can be found at the world’s most exclusive retailers, including Barneys New York, Fred Segal LA and the original Calypso boutique in St. Barths.
