Newly-single American popstar, Katy Perry is as famous for her experimental sense of style as her music. She became a household name with her debut single 'I Kissed a Girl' in 2008. Since then, she's risen to the top of the single and album charts (selling more than 11 million albums worldwide) with her tongue-in-cheek lyrics, become BF's with fellow fashionista, Rihanna, married and divorced British comedian, Russell Brand and appeared as a guest judge on The X Factor. Phew! Katy's now considered one of the most successful female singers of her generation. She describes her quirky, colourful style as "a bit of a concoction of different things" and she's not wrong! Over the years, she's chanelled Manga cartoons, fifties rockabilly, classic pin-up girl and, er, a watermelon. Plus, who can forget that moving carousel dress? We can't wait to see what she'll wear next!
