The Sei

THE SEI is a luxury ready-to-wear LA based collection, founded in 2020, that is fully women and minority owned.

Our small but mighty team of four met while designing at Michelle Mason. When the pandemic upheaved everything, our team suddenly found ourselves at a crossroads on what the future held. While 2020 was challenging, it also allowed us space to step back and evaluate what was important to us.
