Alongside Dries Van Noten, Ann Demeulemeester, Dirk Van Saene, Marina Yee and Dirk Bikkembergs, he emerged "when the idea of Belgian fashion seemed like a contradiction in terms." Issuing his own collections since 1983, he is known for unusual colour combinations and a strong graphic sensibility, drawing on the visual arts, literature, nature and ethnic influences.
His reach extended well beyond the runway: he designed the costumes for U2's 1997 PopMart Tour, was named Cultural Ambassador of Flanders in 1999, and curated the landmark 'Mode 2001 Landed-Geland' project in Antwerp. He also led the fashion department at the Royal Academy of Fine Arts Antwerp until 2022.
