A slew of celebs attended the "PUNK: Chaos to Couture" Costume Institute Gala at The Metropolitan in New York City on Monday night.

Miley Cyrus teased up her bottled blonde hair (featuring dark brown roots) and wore a slinky mesh Marc Jacobs dress.  The singer/actress said her look was inspired by Morticia Adams.

She's not the only star who opted for an unsual and theme-fitting look at the punk-inspired ball.

Like Cyrus, Nicole Richie debuted some interesting hair. She showed up with a short grey look - to which pop star Rihanna responded: "This bitch makes me throw up." But the Barbadian singer meant it in a good way, believe it or not!

Madonna, who has often pushed the fashion envelope over the years, went 100 percent punk. She wore a fishnet body stocking covered by a short plaid, studded jacket. She wore a black wig.
