Vreeland personified twentieth-century American couture and helped transform modern culture. As the innovative fashion editor of Harper's Bazaar and the legendary editor-in-chief of Vogue during the tumultuous 1960s, she redefined women's sense of beauty and style, provoking and challenging accepted ideas in the fashion world and leaving a legacy that resonates today. From Seventh Avenue to leopard print scarves to her red lacquered office, Diana (pronounced DEE-ana, as she demanded) made American fashion relevant. She launched the careers of such luminous beauties as Lauren Bacall, Penelope Tree, and Lauren Hutton, and she knew everyone, including Coco Chanel, Oscar de la Renta, Salvador Dali, Swifty Lazar, Truman Capote, the Duke and Duchess of Windsor, the Kennedys, Andy Warhol, Jack Nicholson, and Mick Jagger. Nearly twenty-five years after her death, this icon of style's influence is more prevalent than ever.
