After channelling her inner Wednesday Addams at the Fortuna Desperata opening night in New York on Sunday evening, it looks like the Firework hitmaker went straight back to the fancy dress shop for her debut at the David Lynch Foundation Benefit Concert.
Katy slipped into this plunging black jumpsuit with a Balmain-inspired gilded waist belt for her appearance - all pretty stylish, don't get us wrong - until she showcased these huge fluttery wings while striking a pose for the paps.
Katy grabbed everyones attention in the rather unusual jumpsuit as she looked a little bit like a cross between a red carpet regular and, well, a bat!
That said, the star who is used to sporting funfair carousels as skirts and apples as handbags managed to pull off her brooding, gothic look, especially as she totally nailed her make-up.
The songstress softened her ensemble with an oh-so-pretty frosted pink pout which offset her otherworldly, flawless complexion, and a cat-eye flick sharp enough to kill!
With her raven tresses slicked back into a simple bun, Katy proved that anything goes when it comes to a celeb bash.
We still can't get enough of her.
