Anna Kendrick: The Up in the Air beauty was breathtaking at the Academy Awards in her pale, pink Elie Saab gown, changing into a high-necked, feathery mini, which covered her chest up in lace. Not an impressive finish to a glam evening.

Amanda Seyfried: Amanda’s Armani Prive Spring 2010 Oscar gown, was absolutely breathtaking. The Dear John beauty changed into a green, Valentino Spring 2010 mini, which looked gorgeous against her flawless skin, but lacked the wow factor of her Armani.

Jennifer Lopez: The gorgeous Latina wore an awkwardly, front-bustled Armani Prive to the Academy Awards, and then changed into a diva-delightful, black cutout for Vanity Fair.

Cameron Diaz: The bubbly blonde made a huge mistake taking off her breathtakingly embellished Oscar de la Renta for a boring, metallic, one-shouldered dress.

Diane Kruger: The Inglourious Basterds star looked glam in Chanel Haute Couture at the Oscars, then showed up to Vanity Fair, in a bra-exposing, red dress.

Elizabeth Banks: The stunning blonde rocked the Oscars in a gorgeous, ruffled Atelier Versace from the Spring 2009 Collection, then changed into a fantastic, modern mini from the same collection.
