It looks like the leading ladies of Gossip Girl have mastered the art of French chic since taking to Paris to film the show’s much-anticipated fourth season. First it was Blake Lively‘s Serena van der Woodsen, whose envy-worthy wardrobe had us swooning. Now, it’s Leighton Meester’s endless parade of Oscar de la Renta on the Parisian set that has us in a fashion daydream. Meester started out in an eyelet-trimmed, lime green jacket and shorts suit from the designer’s spring 2010 collection, but quickly changed to a flirty floral dress–complete with a beaded waistband, orange Nancy Gonzalez bag and matching Christian Louboutin sandals–to shoot scenes outside the Chanel store on Avenue Montaigne. Then, in true Blair Waldorf fashion, the brunette beauty stole the scene in a red-hot tulle ball gown from Oscar de la Renta’s pre-fall 2010 collection. We love how even in Paris, Blair manages to look every bit the Upper East Side sophisticate! Tell us: Whose Paris style do you like better, Serena or Blair?Andrea DeSimone
