When Mr Anthony Vaccarello took the helm at Saint Laurent, he began by scouring the house's archives for inspiration, and you can really see its heritage in this slim-fit blazer. Woven with metallic silver threads, it harks back to the striking pieces worn by guests at the label's famous 'Opium' party in 1978. This piece has been tailored in Italy and is fully lined with smooth satin so that it slips on easily over shirts and sweaters.
