One of the most popular Academy Awards after parties is thrown by Vanity Fair, and tons of A listers attended the festive event on Sunday night.

Commonly, those who attend the biggest event in Hollywood change dresses for the after parties. "Best Actress" winner Jennifer Lawrence (above) left her Dior Haute Courture gown behind and opted for a slinkly metallic floor-length gown.

Anne Hathaway, who was criticized for her pink Prada dress that showed a bit of nipple, chose a pale blue shift dress with a gold sequined collar. The dress matched her Oscar!

Zoe Saldana was included on some worst dressed lists for her lavender Alex Mabille gown. For the Vanity Fair party she opted for a sexy black lace dress.

Plenty of stars who didn't attend the awards show mingled with the nominees and winners, including Natalie Portman and her husband, Selena Gomez and Vanessa Hudgens.
