A hip crowd gathered at West Hollywood hot spot BLT to watch all the action unfold at the 2010 Academy Awards during InStyle's annual Oscar viewing party. Rachel Bilson's favorite Oscar moment? "Ben Stiller was very funny," said the actress. "I love when people don’t take themselves too seriously." One thing Bilson did give some serious consideration to was her Oscar night fashion statement. "I usually go short, so I decided to wear this Zac Posen dress tonight," said the stylish star, who layered on a vintage bolero jacket. "It's so classy and figure flattering."
