In the social world, the equivalent of the post-game wrap-up is a ladies' lunch at Bergdorf Goodman. Or so it seemed when Anne Grauso hosted a gathering for Olivier Theyskens there Tuesday afternoon, the day after the Costume Institute gala.

Tory Burch, Marjorie Gubelmann, Patricia Lansing and Helen Schifter all showed up bright-eyed, bushy-tailed and ready to dissect the fashions from the night before. Even Lauren Davis — who didn't make it home from the festivities until 6 a.m. — seemed ready to face the day. "You don't even look tired," said Jennifer Creel. "It's so annoying."

By that evening, the social swirl had begun anew, as a veritable who's who of fashion and art showed up for the American Patrons of the Tate's first "Artists Dinner," which was held at the Riverfront Pavilion at the West Side Highway. Diane von Furstenberg walked in with Barry Diller, Cindy Sherman arrived with David Byrne and Chuck Close and Robert Rauschenberg were hanging out by the cocktail area together in two very high-tech wheelchairs, looking bemused by the whole thing. "When I was coming up, an art party was people throwing up on one another, and the idea of a supermodel being there was virtually inconceivable," said Close. "I'm not sure this has been a good development."

Others in the crowd included Calvin Klein, Frank Stella, Ed Ruscha, Aby and Samantha Rosen and Valentino, whose fashion house threw a charity luncheon and fashion show at Cipriani 42nd Street on Thursday to benefit the New York-Presbyterian Hospital's Department of Obstetrics and Gynecology. "I gave birth to two children there," explained co-chair Sloan Barnett. Droves of Val's gals, including Jamee Gregory, Eliza Reed Bolen, Emilia Fanjul Pfeifler and Celerie Kemble sipped Bellinis and nibbled chicken and spinach salad while taking in a runway show of Valentino's fall 2007 collection.
