'X-Men's' Superhero Style

Swinging London collides with Marvel comic-book superheroes in 20th Century Fox's summer blockbuster X-Men: First Class. Unlike the franchise's earlier X-Men films, the prequel is set in the early 1960s before Professor X (James McAvoy) and Magneto (Michael Fassbender) became archenemies -- they're just two dapper young men, Charles Xavier and Erik Lehnsherr, who are learning to use their superpowers. "We looked at Sean Connery in the early James Bond films and Steve McQueen in The Thomas Crown Affair," says costume designer Sammy Sheldon, who also worked with director Matthew Vaughn on 2010's Kick-Ass and 2007's Stardust. "Our goal was to create a mysterious, über-fashionable and supersexy world for the mutants."
