Jessica Alba (in DVF) joined Diane von Furstenberg for a night celebrating Girl Power at the Third Annual DVF Awards, held at the United Nations in New York. “My life mission is to empower women,” the designer told before taking the stage to honor five who have demonstrated leadership, strength, and courage in their fields, including Oprah Winfrey.
