In past years, Costume Institute shows organized around famous designers such as Cristóbal Balenciaga, Chanel, Yves Saint Laurent, and Gianni Versace; and style doyenne like Diana Vreeland, Mona von Bismarck, Babe Paley, Jayne Wrightsman, Jacqueline Kennedy Onassis, Nan Kempner, and Iris Apfel have drawn significant crowds to the Met. The Costume Institute's annual Benefit Gala, co-chaired by "Vogue" editor-in-chief Anna Wintour, is an extremely popular, if exclusive, event in the fashion world; in 2007, the 700 available tickets started at $6,500 per person.
