Do you ever wonder why some celebrities look so comfortable wearing couture on the red carpet while millions of people dissect their every move? I credit this impressive feat with the unshakable bond between designer and muse. Although it's hard to tell which came first- did the actress blindly choose the dress or did the designer reach out to the actress? - it's an irrefutable fact that a mutual love between the two is the key to a flawless red carpet moment. The partnership is win-win: free advertising for the brand and tried-and-true glamour for the wearer. In the gallery below, a round-up of actresses in their red carpet second skin. Dior, YSL, Alexander McQueen, Chanel: call me!
