The Best, Worst & Wackiest Fashions Of The Week

By Leah Ornstein - RadarOnline.com Style & Beauty Editor

From the hottest red carpet events in London, New York and the South of France to the city streets, Hollywood’s hottest stars were dressed to rock and shock – and RadarOnline.com has all the photos in our weekly fashion feature.

It was hard to pick a wardrobe winner this week, as several big screen bombshells showed off their blockbuster style. Sarah Jessica Parker looked sexy in the city at Fashion’s Night Out, rocking a lovely leather Prabal Gurung dress, while Gwyneth Paltrow looked pretty in Prada pink earlier in the week at the Venice Film Festival premiere of Contagion. Emma Watson was dressed to thrill in McQ plaid at the GQ Men of the Year Awards in London and Scarlett Johansson showed off her covetable curves in Marc Jacobs at a Moet & Chandon event in Shanghai.

As for style slip-ups, Tara Reid looked like a trashy tourist in London, showing off her panties in her London sweatshirt and dirty denim ensemble and Coco hit Sin City with Ice-T, wearing a boob-baring latex dress.

The wackiest look of the week was courtesy of socialite Daphne Guinness, who dressed up like a nun to honor Valentino at the 2011 Couture Council Award for Artistry of Fashion in NYC.
