At Tuesday's Neue Galerie Winter Gala, partygoers like Aerin Lauder Zinterhofer, Zac Posen, and Craig McDean split the evening between ground-floor socializing and second-level art appreciation—though they were dressed more for the former than the latter. "I just have to stop going up and down in these heels," said Zani Gugelmann. "They weren't made for stairs." Meanwhile, at Donna Karan's Greenwich Street studio, ACRIA toasted Bob Colacello at its 12th annual holiday dinner. Accepting a portrait of himself by the artist Martin Saar, the author reminisced about the organization's first dinner: "As Bridget Berlin gave a monologue on her eating disorders, Nan Kempner and the rest of the uptown ladies I was responsible for bringing to Tribeca sat there not knowing whether they should laugh or walk out." Guests including Francisco Costa, Nicole Miller, and Cyndi Lauper lingered well past dessert to hear Vanessa Carlton perform songs from her new album.
