Dining With Costa
"I'm a total gate-crasher tonight, but I'm British and we somehow get away with it," said Euan Rellie with a wink at the start of the Calvin Klein dinner at the Waverly Inn on Thursday night. The Englishman, who in fact arrived as Kelly Killoren-Bensimon's "date" (having received special dispensation from pregnant wife Lucy Sykes Rellie), was one of a small group of editors and socials who sat down to celebrate Francisco Costa's latest collection. Though it marked the first time that a private affair was held at the see-and-be-seen eatery, most of the evening's attendees were regulars. "I come here all the time," commented Aerin Lauder Zinterhofer, while her tablemate Renée Rockefeller, an unlikely first-timer, recalled reading how her "crush" Owen Wilson had been banished to the back of the restaurant, known as "Siberia." Sitting at Ron Perelman's usual table, Anouck Lepère and Jefferson Hack chatted with Elizabeth Saltzman Walker, while one booth over (Graydon Carter's spot), Costa bonded with Camilla Al Fayed, Astrid Muñoz, and his number one catwalker, Natalia Vodianova. "I feel good," said the designer. "It’s over."

Dancing With Zac
Fresh from his latest runway spectacular, Zac Posen greeted guests at the brand-new D'Or at Amalia, floating in between the lounge's three levels and planting kisses on Fabiola Beracasa, Byrdie Bell, and Rachel Bilson. But once the meet-and-greet was over, he made his real mission clear. "Can we dance already?" he implored. "Let's dance!" He and his guests jumped around as Brooklyn band Stylofone played a set in the cavernous downstairs space. "Now what I really need," the designer said, "is a vacation!"
