Kim Kardashian and her sister, Kourtney, were in London yesterday for the launch of their Kardashian Kollection at Dorothy Perkins. Kim stepped out in a tight black dress that, surprisingly, was one of her own designs for the collection. 

Kim was joined by Kanye West post-launch and the two dined at Hakkasan. The Kardashian Kollection will be available exclusively in more than 200 Dorothy Perkins stores and online.
