1. Jennifer Lawrence in Dior
2013 was a breakout year for this young actress: the star of the Hunger Gamesfranchise and Silver Linings Playbook landed a high-profile ad campaign as the face of the major fashion house Dior. Here, she stunned in one of their creations at the Oscars. The pale pink princess gown is fitted through the hips, giving her an ethereal mermaid look. Lawrence endeared herself to viewers by tripping as she went up the stairs to accept her Best Actress trophy. Fall or not, she still looked like a radiant star.
