Ke$ha's Costume-y Look Tops This Week's Worst-Dressed List (PHOTOS)

The Kids' Choice Awards is a chance to take some risks, but along with daring looks come style slips. Ke$ha showed up looking like something out of "A Clockwork Orange" and Kristen Stewart turned heads in teeny tiny shorts and a pointy shouldered top that was giving off a "Star Trek" vibe.

"Mad Men" celebrated its premiere this week and the stars stepped out looking ... interesting. January Jones took a risk in a sheer-up-to-there dress and Christina Hendricks covered up those gorgeous curves in an awkward frock.

Check out those over-the-top looks, as well as more celebrities who made our week's worst-dressed list. Are we being too harsh? Or do you agree with us?
