American Idol judge Jennifer Lopez Tweeted fans asking for some styling help this week: "What should I wear on @americanidol tonight? #creamwithgold or #sparklywithtulle?" And the winner, as we saw on Wednesday night's show, was cream and gold! Her skin-tight ivory dress with gold buckles was a fresh-off-the-runway look from Hervé Léger by Max Azria's fall 2011 collection (check it out here). The following night, during Pia Toscano's shocking elimination show, Lopez wore a burnt orange blouse by Diane Von Furstenberg ($245 at DVF.com) with layers of necklaces. She also twisted her hair into a high ballerina bun to show off her sparkling dangle earrings. See more of Jennifer Lopez's American Idol looks here.
