Alexander Wang looked to the archives when designing Balenciaga's AW15 collection. The result? Couture-worthy pieces such as this grey-mèlange top. It's spun from virgin wool for a slim fit and detailed with silver staples along the sides – a runway motif that echoes the dressmaker pins Balenciaga himself would have used. Keep things chic with a pair of cropped trousers and pointed leather boots.
