The former president of Puig Group, which owns Carolina Herrera and Nina Ricci, Mario Grauso is a fashion force to be reckoned with. He enticed celebrities like Renée Zellweger and Reese Witherspoon into wearing the daring designs of Olivier Theyskens, whom Grauso brought in as head designer of Nina Ricci. In 2009, Grauso became president of Vera Wang.
