They Wore What?! Major Star Movie Costumes

It's not Halloween for these celebs, who've dressed up as pregnant prostitutes, electrified villains and '70s stunners for their upcoming roles

BRADLEY COOPER & AMY ADAMS

Movie: American Hustle
Foxx isn't the only one having a bad hair day. Bradley gets into the '70s groove in a bright blue suit, loud tie and bad perm to play an out-of-control federal agent trying to nab a crew of con artists. Amy plays the lead swindler's gal pal in a wardrobe we've seen in old family photos. Synthetics never looked so good.
