This week was all about Rachel McAdams and body-hugging bodices. And the winners are...

Rachel McAdams glowing in Alberta Ferretti at the "Sherlock Holmes" premiere in Germany. I take turns between admiring the chiffon draping and the rich teal hue of this dress.

Amber Valletta rocking a RM by Roland Mouret dress at "The Spy Next Door" premiere in Los Angeles. Amber proves she's not afraid to be the center of attention in this bright and bold-shouldered bodice. I also like her nude heel pairing.

Olivia Wilde working it in an Alexander McQueen number at the Fox 2010 Winter All-Star Party. The electric blue shade and sculpted accents on both the shoulder and hip of this otherwise simple dress make it a lot more interesting to look at (and hard to turn away from).

Kim Kardashian posing in a black and white sheath at Ocean Magazine's 17th Anniversary Party. Geometric black and white designs have become so hot among celebs lately, and it's easy to see why. Here, Kim manages to look both classy and cutting-edge.

Rachel McAdams (yes, I'm featuring her twice because she's THAT good) wearing a nude-colored Vionnet Resort 2010 dress at the "Sherlock Holmes" premiere in Madrid. Like her Alberta Ferretti number, this off-the-shoulder dress creates an air of old Hollywood glamour. Just beautiful!
