The celebrity fashionistas put on quite a show for the paparazzi as they arrived at the annual glamour bash on Monday evening, but all eyes were on Holmes, Parker and Anne Hathaway, who topped off an Oscars gold outfit with a hood.

Holmes' new short bob sparked debate as to whether she chopped off her long locks or was simply wearing a wig to the Metropolitan Museum of Art with pal Zac Posen, who designed her sparkly midnight blue gown.

And Parker, who is often the star of the event, stunned with an one-shoulder black gown which she designed in collaboration with designers at popular retailer H&M. She topped it off with an elaborate Treacy number, that made it look as if her scalp was ablaze.

Oscar winner Hathaway's Ralph Lauren gown was bold and gold and featured a hood.

Other stars showing off daring haridos and accessories included actress Emma Roberts, who added chopsticks to her slick bun, Katy Perry, who rocked a pixie cut, and Miley Cyrus, who was bold in her blue dyed hair.

This year’s (15) Costume Institute Gala Benefit is co-chaired by Jennifer Lawrence, who wore a Dior Couture dress, Chinese actress Gong Li and Vogue editor Anna Wintour, among others.
