437 was born in 2016, when best friends Hyla Nayeri and Adrien Bettio found themselves searching for swimwear that truly flattered their bodies, and came up empty-handed. Recognizing a gap in the market, they decided to create something better. With their personal savings and no outside investment, they launched 437 from their university house at 437 Johnson Avenue, all while finishing their final year of school.

From the very beginning, 437 has been about designs that celebrate the body: effortless to wear yet intentional in their fit. What started as swimwear naturally expanded into activewear and lifestyle collections; each new category guided by the same principles. Our pieces have been spotted on Jennifer Lopez, Kylie Jenner, Kendall Jenner, Bella Hadid, Emily Ratajkowski, Megan Thee Stallion, Sydney Sweeney, Alix Earle, Millie Bobby Brown and many more.
