That was the singer's latest incarnation as she appeared on German chat show Wetten, das...? over the weekend. In her homage to Oktoberfest, Perry sported her take on the traditional Bavarian dirndl, which featured polka dots, ruffles, sparkles... and revealed a bit of leg and cleavage (we knew a little Sesame Street debacle wouldn't stop this girl from showing a little skin).
Perry didn't let her sexy ensemble get in the way of her drinking, either, Tweeting before the show: "I'm starving, what should I have for lunch... Beer? Time to bust out my wench dress. God knows I've got the rack for it." And if the bierfest outfit wasn't enough, Perry proceeded to change into a revealing diamanté-encrusted leotard as she performed on the show.
What do you think of Katy's take on the German beer maid look?
