BACK IN TOWN: Talk about a busy schedule. In the past week, Diane von Furstenberg was in Paris, meeting with her new creative director Yvan Mispelaere, then hopped to Los Angeles for her annual barbeque the day before the Oscars, and, on Monday, flew back home to host a party at her Meatpacking District studio to fete International Women’s Day and her first compilation CD, appropriately titled “Proud to be Woman.” “I was definitely wiped after a weekend in L.A., but I could not miss celebrating International Women’s Day in New York and the launch of the CD,” von Furstenberg said. The CD benefits Vital Voices, and the event showcased pieces from Brazilian artist and activist Panmela Castro-Anarkia. Estelle — “the epitome of someone who is proud to be a woman,” von Furstenberg said — DJ’d. The designer’s next big event is just a few days away. On Saturday, she and Tina Brown will host the inaugural DVF Awards at the United Nations.
