The holidays are over and Hollywood’s hottest stars are getting back to business, hitting the streets and the red carpet dressed to rock and shock – and RadarOnline.com has all the wardrobe winners and sinners in our daily fashion feature.

Rooney Mara continued her sensational The Girl with the Dragon Tattoo style streak, hitting the Paris premiere dressed to thrill. The star-on-the-rise rocked a Louis Vuitton cocktail dress with Givenchy heels, scoring herself the best look of the day.

Jersey Shore stars Snooki and J-WOWW experienced boardwalk blunders while filming a segment for Extra at The Grove in Los Angeles.  Both the “guidettes” brought a little too much boobage to the cameras, in their equally sexy style.

Kim Kardashian and Katharine McPhee were flying high on the fashion front during their travels, while Mischa Barton sported clashing fashion as she arrived in St. Barts.
