Mayfair antiques destination Grays hosts a pre-fashion week celebration of vintage style. Head down to catch carefully curated catwalk shows featuring one-off designs from fashion legends such as Ossie Clark, Biba, Yves Saint Laurent and Chanel. The best bit? If a bit of fashion history catches your eye, you can try it on and take it home. You don’t get that at the Burberry show (unless your last name is Delevingne).
