It's safe to say that Jennifer Lawrence is a hearty eater -- and a pretty careless one, at that.

During the discussion on awards-season fashion at Diane von Furstenberg's "Journey of a Dress" exhibit in Los Angeles, costume designer Michael Wilkinson shares the stories behind some of the costumes he curated for the film "American Hustle," which includes that iconic metallic white dress worn by Lawrence's character Rosalyn Rosenfeld.

But the highlight of Wilkinson's talk was the "Hunger Games" actress's rather clumsy ways, especially when eating while wearing the costume.

"Jennifer Lawrence is a very . . . let's say . . . raw and intuitive young lady, and she's not against eating Doritos and snack food in her costume," Wilkinson says. "So we were glad that we had a couple [backups]."

And it was easy to make backups for Lawrence's costume, because the fabric used for it costs only $3.99 per yard. According to Vanity Fair, director David O. Russell intended that Rosalyn's dress looked cheap, thus the choice for a cheap and stretchy fabric.

Wilkinson just confirmed what Lawrence has been doing during the filming of "American Hustle," as narrated to Harper's Bazaar UK.

"My bodyguard Gilbert, right before they call 'action,' I'm like, 'If there aren't Cheez-Its here by the time they call 'cut,' just go home,'" she recalls. "And he'll start running. It cracks me up how seriously he takes it."

Meanwhile, Wilkinson dishes more on the other wardrobe malfunction he encountered at Hustle, most notably Amy Adams' wine-stained DVF dress. According to him, that dress came from a vintage shop somewhere in the Midwest, and it arrived on set with a wine stain on it.

"We thought that we would come up with a back story to justify the stain," Wilkinson said. "Someone left the dress at the dry cleaner, they couldn't get the stain out."
