For the final installment in the Wonder Women series, Diane von Fürstenberg—the woman behind the iconic fashion line—welcomes Katie and Brian to her company's Manhattan headquarters for a conversation about her full and colorful life. They discuss her wide-ranging philanthropy, her famous husbands, and how her brand has evolved since she appeared on the cover of Newsweek at age 29. She also tells the story of her mother, a Holocaust survivor, and how she inspired Diane’s determination to be independent. Plus, DVF explains why she believes the most important relationship in life is the one you have with yourself: “If you have that, any other relationship is a plus and not a must."
