This week was all about gold accents and belts. And the winners are...

Jessica Alba sizzling in a black and gold Balmain shift at the "Machete" premiere in Los Angeles. I like how the actress went light on accessories, pairing her dress with a few bracelets and Christian Louboutin cut-out boots.

Katy Perry rocking a full-skirted number from the Zuhair Murad Fall 2010 Couture "Romantic Intimacy" collection. Between the oversized satin bow and tulle rosette detailing along the skirt, this cocktail dress has "Mad Men" written all over it. I also like how Katy resisted a colorful shoe and opted for something more neutral and equally feminine.

Drew Barrymore shining in a gold Catherine Malandrino gown at the "Going the Distance" premiere in Los Angeles. The actress added an edgy touch to her shimmery sensation with a studded Balmain belt.

America Ferrera glowing in an asymmetrical Catherine Malandrino dress at "The Dry Land" premiere in Miami. Not only does this belted style work well with America's hourglass shape, the cognac shade of this dress is right on trend for fall.

Kim Kardashian working it in a Hannah Marshall bodice at the LA Confidential Magazine Emmy Kick-Off Celebration in London. By using a clear belt, the fab TV star managed to bring attention to her small waist without completely taking attention away from the rest of her look.
