Griffin seems to like his Santa suit and he wears it well, don't you think?
Lizzie on the other hand, hates clothes. She hides in the corner and hangs her head as if to say, "Please, please don't dress me up in a ridiculous outfit!" The most I can get her to wear is a bandana, which Griffin likes to grab and drag her around the house with. (Maybe that's why Lizzie doesn't like him very well!)
