What: A dinner and after-party to celebrate W's September issue and its cover star Cara Delevingne.

When: Saturday, September 14

Where: Ian Schrager's newly opened London Edition hotel

Who: Kate Moss, Damien Hirst, Harry Styles, Tim Walker, Juergen Teller, Kelly Osbourne, her fiancé Matthew Mosshart, and Alexander Wang who took a quick break from working on his Balenciaga collection and flew in from Paris.

Why: Because, as Lynn Hirschberg writes in her story on Delevingne, ever since the rebellious model "arrived in the fashion world four years ago, she was an instant sensation—a face that captivated."
