Sound the Mariah Carey klaxon: the Christmas season has started. The turning on of Stella McCartney’s festive lights at her shop in Bruton Street, London, is the first day of Christmas in the official fashion calendar. Our highlight: a heartwarming girly bear hug between two pop queens. Kylie Minogue (black sequin blazer over silk camisole, boyfriend jeans, black courts) said hello to Neneh Cherry (hooded mohair cloud-grey coat, black skinnies, trainers), who wrapped her arms around her for a cuddle. Who needs mistletoe?
