In 1993 he staged his debut fashion show during London Fashion Week, where Naomi Campbell and Christy Turlington walked his catwalk in return for free hats. In 1994 he opened his first boutique, in London’s Belgravia, and in 2000 Treacy became the first accessories designer to be invited by the Chambre Syndicale de la Haute Couture to show his work during Paris couture week.
Treacy collaborates with some of the world’s finest artists and designers, including Alexander McQueen and Vanessa Beecroft, and his work is displayed in museums such as the V&A; and the Design Museum in London and the Irish Museum of Modern Art. In 2004 he won the Chinese International Designer of the Year Award; 3005 sees the completion of his first interior design project, at The G, a five-star hotel in Galway, Ireland.
