'PUNK: Chaos To Couture' gala nyc fashion red carpet

Madonna was the last star to arrive to the 2013 Costume Institute Gala on Monday night, but as far as we're concerned, she was one of the only celebs who went all out and adhered to the punk theme.

Madge wore a dark wig, a grey studded tartan jacket by Givenchy Haute Couture by Riccardo Tisci and fishnet tights, and the 54-year-old singer accessorized with her 25-year-old boyfriend Brahim Zaibat. That's pretty rebellious, right?
