In 2020, four designers came together to create their very own label. The Sei is an LA-based brand creating ready-to-wear that inspires, empowers, and never ceases to impress. It explores the contrast of strong, structured styles with irresistibly feminine drapes and folds. The end results? Polished classics and captivating silhouettes.

The Sei’s creations are designed for women, by women, to transcend generations and lifestyles. They range from lustrous silk sets and show-stopping gowns to endlessly versatile essentials.
