02/23/09 - Madonna, Rachel Weisz, Victoria Beckham... nobody wanted to miss the best post-Oscar parties. We´re going to tell you all about the parties and what the celebs wore, from Madonna to Gwen Stefani.

One of the most important parties on Oscar night is the Vanity Fair event, which dates back to 1967. Its red carpet is almost as famous as the gala itself.

The other big party is Elton John´s... For everyone who´s anyone in Hollywood it´s unmissable.

This year we saw celebs like Jada Pinkett-Smith, who wore a crystal-studded Roberto Cavalli Resort dress. Kate Beckinsale is still a fan of black for parties, dressing in J. Mendel this time. Rachel Weisz went for a great Narciso Rodriguez number and Gwen Stefani attracted lots of media attention with her Chanel cocktail dress.

Naomi Watts´s glamour and unique elegance was sorely missed, while Jessica Biel changed into an Oscar de la Renta dress for the VF party and Madonna went for a rounded bracelet clutch.
