Four years ago, Michelle Obama launched then-little-known designer Jason Wu into the spotlight when she chose to wear his one-shouldered white gown to the Inaugural ball. Since then, his career has taken off--in addition to presenting successful and critically acclaimed ready-to-wear collections he's launched a collection for Target and a contemporary line. Four years later, after lots of anticipation about which new young designer the First Lady might anoint with her choice of ball gown tonight, she's chosen Wu once again.
