No one had more fun at London Collections: Men than Wiz Khalifa. While others primped and preened and jostled to catch the eye of each passing street-style photographer, the Pittsburgh rapper simply stepped into some sweet streetwear, adopted an air of relaxed amusement and breezed through a busy schedule of shows and parties looking like an absolute champ at all times. As well as a lesson in not taking style too seriously, Khalifa offered a masterclass in packing lightly but wisely for his long weekend in London, transforming a few key items into an arsenal of admirable outfits.
