This week was all about taking chances. And the winners are...

Emily Deschanel in BCBG Max Azria at the 2011 Fox All-Star Party. Good girl meets bad girl in this lace and leather-trimmed dress, which happened to be my favorite from the event. I also like how Emily mized things up with square-toe pumps, which seem to be making a comeback for spring.

Natalie Portman in Vena Cava at the "No Strings Attached" premiere in Los Angeles. Not only did this gown succeed in concealing Natalie's baby bump, but the color blocking and cutout detail oozed boho chic.

Lake Bell in Basil Soda at the "No Strings Attached" premiere in Los Angeles. The actress stole the spotlight in this body-hugging bodice, which she topped off with a pair of nude, ankle-strap platforms.

Rachel McAdams in Michael Kors at the "Morning Glory" premiere in Berlin. The actress looked like a Grecian goddess in this beautiful, breezy halter gown with black leather trimming.

Michelle Williams in Oscar de la Renta at the 2011 National Board of Review Awards Gala. Michelle has a penchant for retro (and often lacy) styles with a modern twist, so when it came to dressing for the awards gala, this dress was probably a no-brainer. She wrapped up her romantic style with a satin bow and platforms.
