I recently stopped by Chelsea's Saatchi Gallery to visit The Little Black Jacket photography exhibition. Coco Chanel's iconic tweed jacket has transcended fashion to become a style staple. 113 photographs portray the jacket in a range of guises and feature models, actors, hip-hop stars, fashion editors, children and TV personalities. Photographed by Karl Lagerfeld and styled by French Vogue's Carine Roitfeld, the message is clear; the jacket can be worn by everyone.
