Angus Tsui is a true pioneer of sustainable fashion. He might have caught your attention when he made Chinese New Year envelopes out of old Cathay Pacific cabin crew uniforms, but the designer’s upcycling and zero-waste initiatives inform every piece of edgy men's and women's clothing he makes. That’s just one reason why celebrities and fashionistas have fallen in love with his work. The brand launches trans-seasonal collections once a year to slow down the pattern of mass consumption, while made-to-order is available at its studio. Among other side hustles, he runs an educational charity project devoted to sustainability.
