Celebrity Christmas 2011: Stars Dress Up For The Holidays (PHOTOS)

'Tis the season to be jolly, and for many stars that means going all out when it comes to holiday outfits.

Jessica Simpson, Mariah Carey and Justin Bieber have all rocked some festive looks over the years, but it's clear that when it comes to dressing for the holidays, Katy Perry takes the cake. From her toy solider costume to a snowman dress, Perry has set the bar pretty high for other celebs hoping to ramp up their holiday cheer.

We were also quite impressed with the "tacky sweaters" worn by Snoop Dogg, Taylor Swift and, most recently, Matt Damon. We'll be sure to extend some invites when next year's parties roll around.

Check out photos of celebrities getting into the holiday spirit below!
