What to wear: You can either be pre- or post-fame Ally. For the former, wear a plain t-shirt or tank-top knotted at your waist, with striped pants and some kind of metallic accessory — a chain belt, a simple necklace, and of course, a microphone. For Ally post-stardom, you'll either need to dye your hair Tang-orange or find a wig in the same shade, and then put on some flashier, pop star-appropriate garb.
