Kate was looking every bit the supermodel when she left her home earlier today to go promote her new collection at Topshop in London. Ms Moss was actually the mannequin in the Oxford Street store! The crowds were outrageous and apparently shoppers were only allowed to buy five items at a time (most likely to prevent them from being sold on eBay)! We can't wait until she brings the clothes stateside at Barneys NY on May 8th! For more about the UK event, plus pics of Kate in the store window and her adoring fans, just click here.
