Miley Cyrus looked grungy and glamorous at the Costume Institute Gala in New York City May 6. Rocking a spiky blonde 'do, the 20-year-old singer wore a full-length mesh gown by Marc Jacobs. "It's so perfect for tonight," Cyrus told "I'm feeling so good and so punk!"

Cyrus likened her look to Morticia Addams from The Addams Family. "I wanna wear this every day," she said. "It was amazing to not have to try things on a million things. . . This was the first [dress] and [it required] no alterations, which is rare. We put it on and were like, 'We love nights like this where things are just perfect and you just know what's right.'"

This year's gala celebrates the opening of the Punk: Chaos to Couture exhibition. "I got it easy tonight because the dress is so punk in itself," Cyrus said of her look. The So Undercover actress got ready for the event with her costar and BFF Kelly Osbourne, who also donned Marc Jacobs.
