Paul Poiret’s famous Thousand and Second Night soiree in 1911 and Truman Capote’s 1966 Black and White ball are the stuff of fashion lore. We can relive them through Bals: Legendary Costume Balls of the Twentieth Century, for which historian Nicholas Foulkes researched nine of the most glamorous events, including first-person accounts from attendees like Jacqueline de Ribes and Marisa Berenson. We especially love the cover image of Lee Radziwill, one of Capote’s swans, adjusting her beaded mask.
