When Marc Jacobs sent models down the catwalk (or round the carousel, to be precise) wearing huge feather headpieces during his final show for Louis Vuitton in Paris, it was one look we imagined would remain on the runway. Those towering headpieces are hardly practical. But we hadn't reckoned on Lady Gaga, who lives for looks like this! She re-created the memorable show on the slightly less glamorous pavements of London this week, visiting the ITV studios wearing the headpiece with sequinned graffiti trousers and a beaded sheer top. We only have one question: if Gaga dresses like this on a daily basis, what does she do on Halloween?
