The posh London eatery at the Ivy Club is accustomed to a boldfaced crowd. But there were more glam fashion types than usual packed in on Sunday night for the dinner that Sir Philip Green hosted to celebrate his Topshop Unique show: Natalia Vodianova, Naomi Campbell, and Dree Hemingway sat in one corner; Alexa Chung, Vivienne Westwood, and Henry Holland in another; and smack-dab in the middle was Vogue's Anna Wintour, flanked by Burberry's Christopher Bailey and Kate Moss. Even the notoriously hard-to-please Simon Cowell was impressed: "There are some pretty birds here," he was overheard telling a friend.

Dinner conversation stuck to the obvious: Topshop. At one point, Lily Donaldson, Julia Restoin-Roitfeld, and Jacquetta Wheeler were all comparing their high street duds: Donaldson in Kate Moss for Topshop, Restoin-Roitfeld in Christopher Kane for Topshop, and Wheeler in the main line. One person dared ask La Moss what she was wearing, and it didn't end well. "What do you think I'd be wearing?" she shot back, two packs of Marlboro Lights in hand. But Sir Philip was much more chatty, especially about the British Fashion Council's 25th anniversary. "The people in this room are why London fashion is so important," he said, noting that he was happy that the likes of Bailey and Matthew Williamson had returned. "Hopefully, this is a start for more designers to come back, to make London great again."

The night ended with a surprise concert on the top floor of the Ivy. "Don't worry, it's not Simon," Green jested at the start of dinner. In fact, it was Bryan Ferry, and his intimate set had practically everyone marching up the staircases. "Vivienne Westwood's hair whipped me in the face when she went for the dance floor," Leigh Lezark laughed. "Which was completely OK with me."
