Jennifer Lawrence has just begun a major red-carpet marathon. After last night’s opening of The Hunger Games in Los Angeles, the actress will head to London, Paris, and Berlin to promote her new mega-movie. According to her short-ish track record, Lawrence has proved she's not afraid to take risks in front of the cameras, wearing everything from dark and frilly Louis Vuitton at the 2011 Golden Globes to sleek, tomato-red Calvin Klein at the Oscars. For last night's event, she chose a far-from-safe gold lamé Fall 2012 Prabal Gurung gown, with ab-revealing cutouts and an Angelina Jolie-esque slit up the side. Click ahead to see her style evolution and stay tuned to see if the sartorial odds remain ever in her favor as she flits from premiere to premiere.
