Try to think back to the first time you ever heard about Katy Perry. Her "I Kissed a Girl" days are long gone—six years gone to be exact. In that time, Perry has gone from the wild party girl next door to an eclectic style icon. Today, we're celebrating the popstar's style evolution in honor of her 30th birthday. On her big three oh, we're expecting Perry to arrive to her own party in a totally outrageous look fit for a California Girl. So, miss Perry, pop your confetti, pop your Pérignon, and have the best b-day ever.
