Karlie Kloss–currently one of the world’s biggest models and teenage face of Christian Dior–closed the label’s Spring 2012 show yesterday, her ass on display in a sheer gown with floral bodice. Two relevant pieces of information for you: 1) Karlie Kloss is of age now and she wants you to know it and 2) this is the second time we’ve used “butt” in a headline today, so we’re pretty pleased with ourselves.
