Katy Perry
When Katy Perry first showed up on the music scene she had more of a vintage, Betsey Johnson look. Now, the pop star has sexed up her style, stepping out in spandex dresses and skin-baring ensembles. However, Katy also isn't afraid to step out in a banana or snowman costume either. In addition to her clothing choices, she has come out with her own perfume called Purr.
