J-Law's Biggest Fashion Regret?

When Jennifer Lawrence took the stage to pick up her well-earned Best Actress SAG Award for Silver Linings Playbook, it appeared as if she had a wardrobe malfunction, with her dress coming apart at the seams. The world later learned that the dress was designed to do that, but at Monday's annual Oscar Nominees Luncheon, Jennifer explained thatshe wishes she could "take that back."

"The fashion moment that I wish I could take back was accepting the SAG Award and the bottom of my dress falling off," she says with a laugh to ET's Nancy O'Dell."I would definitely take that back. It didn't really fall off, it just gave the appearance of falling off, which is just the same. ... You can't put a tier dress on somebody that walks like a linebacker."
