Say what you want about Katy Perry but she sure knows how to make people talk about her. Hitting the stage at the Y100 Jingle Ball 2010 at BankAtlantic Center, Katy dresses up like some sort of sexy Mrs. Claus, but I can’t help but think someone in the wardrobe department got fired for forgetting to finish Katy’s skirt. At least Katy was wearing festive panties to go with the outfit. Would’ve been pretty embarrassing if she decided to wear her Grannie panties. Just kidding, of course. I sincerely doubt Katy owns Grannie panties. In all honesty, I’m not really feeling the whole half skirt look. I guess she wasn’t showing off her upstairs enough so she had to put the downstairs on display. That’s just the way she rolls, after all. She still looks hot, but I think she would’ve looked hotter if she decided to cover her panties.
