Company: LVMH Moët Hennessy Louis Vuitton
Current CEO: Bernard Arnault
Unlike some heiresses, Delphine Arnault, the hyper-elegant daughter of Bernard Arnault, has more than style. (Though she also has a lot of that too.) Arnault, a London School of Economics graduate, is deputy managing director at elite clothier Dior. After a stint at McKinsey, she was also appointed to the board of directors at LVMH at age 28, where she was the only woman. Those high-powered positions have primed speculation that she could eventually inherit the reins to her father's multinational luxury empire.
