This week was all about texture and sparkle. And the winners are...

Michelle Williams glowing in Jason Wu at the Venice Film Festival. Between the chiffon bow along the neckline and allover beading, this champagne-colored gown (from the designer's Resort 2011 collection) is the epitome of glam.

Leighton Meester rocking a teal Versus mini with cutouts at Fashion's Night Out: The Show. The "Gossip Girl" star's Christian Louboutin ankle boots add a sporty kick to this edgy number.

Dianna Agron posing in Carolina Herrera at the "Glee" Season 2 screening premiere in Los Angeles. The bright yellow hue and bold, black embroidering along the neckline offer a fresh take on this otherwise retro dress.

Blake Lively sparkling in Chanel at the Chanel Soho Boutique Re-Opening. While, at first glance, I didn't quite know what to make of this dress, it didn't take me long to fall for the deep shades of purple and allover sequin detailing. It's definitely a new look for the actress.

Rachel Bilson sporting Chanel at the Chanel Soho Boutique Re-Opening. Long pieces of black and white fringe add more dimension to the otherwise flat color and shape of this dress.
