Katy Perry has become a fashion icon since emerging on the scene and exploding into the mainstream consciousness in 2008. She's rocked every look (and hair color) under the sun, going from girlish and flirty to glammed out to candy-coasted to rocker chic to custom couture, changing her look to suit her whims and moods.

We're looking back at Perry's style evolution over the past five years, admiring her fearlessness when it comes to changing her hair shade and clothing choices, which show off that enviable, curvaceous figure. Perry isn't afraid to play with bright colors, short hems or dangerously high slits.

The only constant for her is that she changes up her look -- a lot -- and she is unpredictable when she hits the red carpet, making her one to watch at all times.
