The Best-Dressed Stars This Week: 12/6/13

Crop-top turtlenecks, ladylike tulle dresses, and head-to-toe lace ensembles were huge this week! Take a look at the ladies who stole the fashionable show.

Karolina Kurkova looked ready for a holiday party in this David Koma red mini dress with a mesh panel to a private dinner hosted by Swarovski in Miami.

Living for Bar Refaeli in Michael Kors' lace tunic and matching trousers. A hard one to pull off, but so worth the risk.

Chanel moment! Keira Knightly was the epitome of princess-like perfection at the SeriousFun London Gala.

Dear Sandy, you just keep getting better and better. The Gravity actress looked lovely Roland Mouret's 'Breccia' dress during a press conference for her movie in Tokyo.

Emmy Rossum paired her femme Oscar de la Renta frock with a bold red lip and Doves by Doron Paloma jewelry to the August Osage County screening.

Things I want right now: Zoe Saldana's Elie Saab black cocktail dress with sheer cut outs and those red booties.

Naomie Harris' parade of winning red-carpet looks during her promotion tour for Mandela: Long Walk Home was amazing to witness, but this navy Vionnet gown stood out from the rest.

Nicole Richie worked a winter-white long skirt with her Lovers + Friends 'Dream On' cropped turtleneck for a sophisticated, yet bohemian, look.
