Rogan Gregory, Kim Gordon, Ryan McGinley, and Claire Danes sipped Champagne at Opening Ceremony last night while they gawked at the store-exclusive line of Nike x Liberty of London floral-print Dunks. "It's such a perfect partnership for us because when we launched the Chloë Sevigny line, her first words were, 'I need Liberty prints,' and it's all over her collection," said Opening Ceremony co-owner Humberto Leon. "Most athletic shoes for women aren't that good and the guys get the best colorways, but taking the feminine theme so far actually works and looks cool." So cool, in fact, that we're sure men will be lining up to get the limited-edition kicks, but they'll have to have small feet: The shoes go up to size 12 women's, which is roughly 8 1/2 men's. One guest not poring over the shoes but chatting it up was Danes. "I'm not really a sneaker fan. I'm an Humberto fan and Opening Ceremony is just the best store. I shop here a lot," she said. Any favorites? "Alexandre Herchcovitch," she said. "But I just like how well the store is curated overall." Come September, the selection at Opening Ceremony will become even stronger with the launch of 15 Japanese designers. And as for the Olympics—which loosely inspired the store's name—Leon promises they will be hosting "something amazing" for the Beijing games.
