What a lovely little lady Hayden Panettiere has become! While most other stars showed up to Z100's Annual Jingle Ball [1] in casual gear, the petite actress stepped it up a notch in a dramatic white ruffle blouse and black pencil skirt. Some may say she's a tad overdressed for the occasion, but I say more power to her. . . . this is how fashionistas ought to differentiate themselves from the masses.
