Cara Delevingne's uniform of trainers, joggers and baseball caps isn't one she often deviates from, but when she does, then boy, she does it in style. Take last night for instance, when Cara attended the J Crew and Vogue bash to celebrate London Fashion Week, and channelled her most fearsome 70s power bitch (slash Tom Ford SS15) in a double-breasted, midnight-blue velvet blazer. Matched with Burberry deep red velvet sandals, a red lip and basically nothing else, lady C has singlehandedly opened a world of outfit inspiration for this weekend. Thanks! The slight whisper of stink-eye is merely an optional extra.
