This week was all about the 2011 Oscars. And the winners are...

Cate Blanchett in Givenchy. The actress exuded elegance in this heavily beaded (and pleated), pale lavender and yellow gown from the designer's couture collection.

Mila Kunis in Elie Saab. Allover lace and chiffon paneling added extra dimension to this whimsical, periwinkle-perfect creation, which was banded at the waist to highlight Mila's feminine figure.

Camila Alves in Zuhair Murad. Camila was nothing short of breathtaking at the Vanity Fair Oscar Party in this nude, sheer-overlay gown with beautiful black flower embroidering throughout. 

Sandra Bullock in Vera Wang. A cutout corset upped the ante on this red-hot fishtail gown, which was wrapped up with a giant bow in back.

Jessica Biel in Atelier Versace. Jessica stole the spotlight at the Vanity Fair Oscar Party in this shimmery, silver and gold-paneled sensation.
