It’s been a big week for Kanye West. He had to accompany his wife (and the most photographed woman on the planet) Kim Kardashian to the fashion world’s biggest annual shindig and not get totally upstaged by her basically see-through Roberto Cavalli dress. This he achieved admirably in an all-velvet tux but, away from the Met Gala red carpet, he was understandably keen to relax and dress down.
