There are few cultural icons from our childhood more beloved than Mary Kate & Ashley Olsen . The bevy of movies the twins put out in the early 2000's, their stints on TV, the branded merchandise (a Walmart clothing line, Barbie dolls)...we could go on and on. In their second stage of life (read: the post-NYU years) they've taken over the fashion world with designer label The Row (and it's younger, bohemian sister, Elizabeth & James), and have become style icons at the ripe age of 31 ( their lewks are always next-level ). Safe to say, their trajectory from child stars to business women has been impressive.
