Christina Aguilera: TO look like Christina Aguilera you need a simple solid black dress and cut it up. Wear strappy black sandals with fishnet tights. Top it off with a fake chin and nose ring. Thanks to Maya for this pop diva idea. Diva Microphone Headpiece No matter which Diva you want to be, the microphone headpiece is a must! Adjustable headpiece with earpiece and faux mircrophone will give you that Rock Star touch! One size fits most (headpiece is adjustable).
