Try to peel your eyes off Katy's bangin' bod, in this UK/US rubber dress, and get a whiff of her tripindicular shades. Lime green Prada shades, to be exact. They looked pretty dope in Prada's island chic ads, and they look even more fly in person, on stage, on Katy. Eighties-inspired sunglasses have serious staying power — especially when they look this good.
