Christopher Kane is fashion's master of the remix, giving old ideas a new spin, although with his new Pre-Fall collection the most striking idea was only as old as his Fall '14 collection. That show's stunning finale, leaves of organza fluttering like the pages in a book, was revisited here in dresses with cutouts folded back like sheets of paper. Given that the exterior was black, the interior pink lent the effect the visceral impact of a fashion autopsy. Kane was enchanted by such a disturbing notion.
