About the brand
THE SEI is a luxury ready-to-wear collection founded in 2020 by four designers who met while working at Michelle Mason. Based in Los Angeles and fully women and minority owned, the brand emerged during the pandemic when the founding team found themselves at a crossroads but chose to stay together, recognizing their complementary strengths and shared vision for creating thoughtful pieces designed for women, by women. The brand builds a foundation of polished classics mixed with seductive silhouettes, empowering women to feel confidence and joy while remaining effortless and timeless. THE SEI's designs masterfully juxtapose masculine restraint in structured pieces against feminine sensuality in draped styles, exploring the contrast between strong, structured designs and irresistibly feminine drapes and folds. The collection spans all generations and lifestyles, ranging from lustrous silk sets and show-stopping gowns to endlessly versatile essentials, creating ready-to-wear that inspires, empowers, and consistently captivates with its polished classics and captivating silhouettes.
