24. Dylan Lauren
Famous Family: Fashion designer Ralph Lauren (father)
Dylan Lauren has done for candy stores what her dad, Ralph, did for khakis: classed 'em up. In 2001 she opened the world's largest candy store, Dylan's Candy Bar, in New York City. Since then, the self-described "Candy Queen" has expanded the chain—which boasts more than 7,000 kinds of candy from around the world—to include outposts in The Hampton, Houston and Miami Beach.
