The Costume Institute Gala at the Metropolitan Museum of Art, also known as the MET BALL boasts as fashion's most fashionable night. If Fashion's Night Out is for the people and consumers of fashion, Fashion Week is for the designers, well the Met Ball is for those who are fashion. The guest list ranged from A-List celeberties to fashion icons. Here are some of the best and the worst of the Met Ball.

Anja Rubik. One of our favorites.

Anne Hathaway rocking her new blonde hair. After winning the Oscar for Les Mis, and already gracing the cover of Vogue twice, she seems unstoppable. One of our favorite looks of the night. If you didn't know the MET GALA'S theme this year was a a tribute and retrospect of punk.

Les Mis co-star Amanda Seyfried.

Katy Perry.

Anna Wintour in Chanel, of course.

Ummm, basically the classier conservative version of Beyonce's dress from last year? Fail.

Sofia Coppola and Marc Jacobs, he is Comme de Garcons.

Nicole Richie, silvered out. Love.

Ummm, no words to even describe what Madonna wore.

Jennifer Lawerence looked stunning and chic, as the newly crowned best actress takes a jab at fashion icon, and head of Halston Heritage, Sarah Jessica Parker. Who knows what the Sex and the City star/ Glee's fashion advocate was thinking... Maybe a tribute to Cher?
