Organized by Capote himself, the party was a black and white ball in which guests were requested to wear masks.
During the Summer of 1966 Truman Capote had to leave New York since he was getting a lot of invite requests for his Masked Ball. Some were not pleased when in the end they were not invited by Capote that they decided to pose on the cover of Esquire "complaining" about it.
Among the 540 guests of this evening were: Gianni Agnelli and his wife, Richard Avedon, Cecil Beaton, Candice Bergen, Harry Belafonte, Marisa Berenson, Leonard Bernstein, Elizabeth Taylor, Richard Burton, Mia Farrow, Frank Sinatra, Andy Warhol, Sammy Davis Jr., Marlene Dietrich, Oscar de la Renta, Gregory Peck, and Penelope Tree.
The party lasted till around 3 AM, a little after Frank Sinatra and his wife then, Mia Farrow, left the Plaza.
