When they wore it: The "Nashville" star stopped by "The Late Show With David Letterman" in the form-fitting frock on August 28. The former "American Idol" judge hit the town a mere three weeks prior and practically looked like she could be Panettiere's doppelganger.
How they styled it: The "Starships" performer worked her curves in the dress and looked more demure than normal with a tame, blond wig, minimal jewelry, red pumps, and a pale pink pucker. The 24-year-old actress kicked up her heels in a pair of red booties, gold bangles, ruby red lips, and a brand new hairdo. Panettiere debuted her blond, blunt bangs and choppy cut during her appearance.
