Katy Perry goes bra-less

Katy was seen clutching a feather to polish off the look with her rose brown dress and pearls

Being in the public eye often requires the art of reinvention.

And Katy Perry certainly commanded attention this evening in a sensational flapper dress.

The Firework singer attended a party held by the City of Hope's Music And Entertainment Industry Group in which this year’s Spirit of Life award was presented to Bob Pittman, Clear Channel CEO.

Tapping into her Twenties fashion flair, Katy stepped out in a burnt rose satin floor-length dress.

The spaghetti strap gown was detailed with lace and pearls on the upper bodice and snaking around the side panels to the back, with Katy appearing to go braless beneath.
