'American Hustle' Stars Take Us Inside Film's 'Dirty' Fashion

Jennifer Lawrence, Amy Adams and Jeremy Renner reveal their thoughts on their sometimes-revealing costumes in the movie.

They say that the clothes make the man, and in the case of the upcoming "American Hustle," the cast is in full agreement.

The new film from director David O. Russell ("Silver Linings Playbook," "The Fighter") not only boasts an all-star cast (how do Amy Adams, Christian Bale, Bradley Cooper, Jennifer Lawrence and Jeremy Renner ring your bell?) but an eye-popping assortment of late-'70s costumes. Everything is over-exaggerated: the cleavage, the combovers, the bouffants.

MTV News recently sat down with the cast of "American Hustle" and grilled them about how their characters' polyester monstrosities helped put the actors into the mindset of the story.

"I think it just helps inform the character every time you can put it on," Adams said, crediting costume designer Michael Wilkinson and director Russell for pulling together an immersive landscape, clothes included, for the actors to inhabit. "It's just another piece of the puzzle."

She did admit, however, that "it feels kind of dirty to see that poster at a bus stop." That would be the one with Adams dressed in a gunmetal concoction with a J-Lo-esque cleavage slit down to her midriff, if you were wondering.

Renner, who plays the crooked-yet-lovable mayor of Atlantic City, said that he didn't mind wearing the costumes, floppy bow ties and all.

"You just kind of give up any ego and just go for it," he said. "I love that, I love that attitude."

Lawrence also acquiesced to the costumes: "I normally wear bras," she revealed dryly. The same is not so true for her character.

"American Hustle" hits theaters Friday.
