The holiday season is in full swing, and practically every night is filled with one festive gathering or another -- office parties, house parties, blah blah blah. It's a time of year that presents a particularly difficult challenge for those who are stylishly inclined -- how do you look fun and festive without going overboard? No one wants to be a Scrooge for the sake of fashion, but no one wants to be that guy at the office Christmas gala who wears the blinking, singing, Santa sweater that makes everyone cringe.

If it's any consolation, celebrities have the same problem. There's tons of parties, events, and functions during the month of December, and your favorite actors, models, and designers are all working to find just the right balance of high fashion and holiday cheer.

Are they up to the task? You be the judge. Check out these celebrity holiday looks, and then vote on whether they're hot...or not.
