Anna Kendrick wore two sexy black dresses on Oscars night, but which looked best on the Pitch Perfect actress?

For the Oscars red carpet outside the Dolby Theatre, Kendrick, 28, wore a black J. Mendel gown with sheer insets along the top and midriff. The dress also featured a side slit, making it all the easier for Kendrick's right leg to peek through a la Angelina Jolie at the 2012 Oscars.

"Weird that no one gave me the memo about wearing a white sparkly dress… Can I not sit at the cool kids table? #Oscars" Kendrick Tweeted on Sunday night. Fans of the gown can pre-order the look on ModaOperandi.com. However the designer dress doesn't come cheap; it retails for $8,200.

The Up in the Air star changed into a sexy Versace Couture gown with black beading and a halter neckline for the Vanity Fair Oscar party in West Hollywood. She styled her hair down and in loose waves -- a more relaxed style from her glam updo that she had for the red carpet.
