Katy Perry has a new retro look!

The singer, who had been experimenting with a goth style, showed up to a City of Hope event in Los Angeles last night rocking a flapper look right out of "The Great Gatsby."

Sporting finger waves, a headpiece in her hair, pearls and a dress that almost looked like a nightie, we think Perry looked great with this sexy new getup.

Once inside the event, Katy let her long hair down and changed into a simple black dress.

Which look do you like better on her? Sound off below!
