Justine Picardie (born 1961) is a British novelist, fashion writer and biographer.
Picardie is a former editor-in-chief of Harper's Bazaar UK and Town & Country UK. Her 2010 biography of Coco Chanel, Coco Chanel: The Legend and the Life, was shortlisted for the Galaxy National Book Awards. A long-time question among fashion historians and experts about whether the famous pink Chanel suit of Jacqueline Bouvier Kennedy was made by Chanel in France or a quality copy purchased from New York's semiannual Chez Ninon collections was resolved by Picardie, who showed (as written in PicardieâÂÂs 2010 book Coco Chanel: The Legend and the Life) that the suit was a garment made by Chez Ninon using Chanel's approved "line for line" system with authorized Chanel patterns and materials.
Picardie's sister was writer Ruth Picardie.
PicardieâÂÂs elder son is Jamie MacColl, the guitarist for Bombay Bicycle Club.
