new york city met gala Charles James: Beyond Fashion Costume Institute Gala Kristen Stewart

A sweatshirt? To the Met Gala? What was she thinking?!

After walking the red carpet in a Chanel dress and Christian Louboutin heels at at the 2014 Met Gala held at the Metropolitan Museum of Art , Kristen Stewart swapped the couture for Converse, jeans and a sweatshirt for the famed event's after party. Oh Kristen you and your devil-may-care attitude are just so rebellious!

A sweatshirt? Jeans? Converse? Clearly visible Vans socks? This is a slap in the face to fashion! Hey Kiki, we know you love to go to premieres in fancy duds and then change into your comfy outfits but just grin and bare it for a night! We're sure Chanel, whom Kristen is the face of, loved the fact that she switched up her look.

The annual event, held at the Metropolitan Museum of Art on Monday in New York City, is the Super Bowl of fashion. All eyes are on the red carpet to see which A-listers sink or swim in the sea of fashion. The star-studded after party was at the Boom Boom Room at the Standard Hotel.

We just hope she avoided Anna Wintour all night. We're pretty sure that cold fish couldn't have loved this dressed-down look at fashion's biggest night.

The Costume Institute Gala Benefit celebrates the opening of the exhibit, Charles James: Beyond Fashion, and was co-chaired by Wintour, Bradley Cooper, Sarah Jessica Parker and other luminaries.
