Katy Perry amfAR's Inspiration Gala - P 2012

The pop singer ditches her usual teeny-bop cartoon character look for a style closer to Florence Welch -- ethereal.

Her hair's been blue, pink and purple -- not to mention blonde -- and she's certainly worn some crazy crazy looks on stage. But when she performed for the A-list entertainment biz crowd at Thursday night's amFAR gala and tribute to CAA's Kevin Huvane, Katy Perry looked a bit like she was emulating Florence Welch from Florence and the Machine, in a floor length long-sleeved taupe, ivory and pink Naeem Khan spring 2012 gown.

Her hair was black and waved, her makeup for subtle than usual -- and her voice in fine fine shape. The choice of dress was a good one -- it was semi see-through and Katy always goes sexy, it was embellished and fun - but it was more diva than teeny bopper.

The look helped Perry fit in in a crowd that featured Sarah Jessica Parker (in Chanel), Kate Hudson (in Prabal Gurung), and a good deal of CAA agents. If she ever wants to act in movies, this is a crowd worth showing another side to.
