In addition to tomorrow's for-pay Street Fighter outfits, Sony will be gifting LittleBigPlanet fans with the first part of a free, two-piece SackSanta costume for your SackBoys (or SackGirls). Stage one is the Santa suit; the hat and beard will be available on the PlayStation Store (again, for free) the following Thursday, December 18.
Like the milk & cookies you leave out for the real Santa, this costume will magically disappear from the PS Store come January 8. We're assuming it won't be replaced with a coal costume.
