THE SEI for Women

THE SEI is a luxury ready-to-wear brand based in Los Angeles, founded in 2020 and fully women- and minority-owned. Born from a team of four designers who met at Michelle Mason, the brand blends diverse perspectives to create timeless, thoughtful pieces for women of all generations. THE SEI balances polished classics with seductive silhouettes, juxtaposing structured, masculine restraint against draped, feminine sensuality. Focused on confidence, joy, and effortless elegance, the collection celebrates versatility and empowerment, offering designs that are both contemporary and enduring.
