People and US Weekly have addictive features called "Who Wore It Better," a style showdown where celebs in the same dress get graded. But why do stars wear the same clothes, especially designer clothes? The last time you showed up to a party in Miu Miu, did anyone have the same thing? Probably not. And while Los Angeles is a small place, and celebrities do often shop the same stores - Milk, Lisa Klein, Max Field, Satine - it's still awfully weird. Until you realize that most celebrities get their clothes for free, either from stylists or from publicists. And if a new dress is gifted to one starlet, it's usually sent to them all. So will celebrities start shopping for themselves? Probably not. In real life, it may be considered uncool to wear the same dress as another girl, but in Hollywood, it's just another excuse to have your photo taken. In fact, we heard from a celebrity publicist this weekend that on occassion, celebrity "friends" plan such double-dressing outings for magazines. But every once in a while, the celebrity double is really a matter of chance - remember when Reese was told her Chanel dress was vintage, when really, Kirsten Dunst wore it two years before?
