Anne Hathaway turned a lot of heads at the Met Ball, for reasons both good and bad.

The 30-year-old was one of hundred of celebs who turned out for the Costume Institute Gala at the Metropolitan Museum of Art in New York City last night, May 6, to celebrate the opening of the Institute's annual fashion exhibit.

First you notice her shocking platinum 'do. The Academy Award winner seems to be channeling Billy Idol with that haircut.

Then you notice the vintage Valentino dress, which, paired with her bleached coif, does seem to invoke punk to match the gala's theme this year.

But then you notice that the gown has transparent, mesh panels — which exposed more than a little side-boob and almost gave away all the goods!

Check out the video for footage of the near-disaster!
