It's a santa suit, costume, outfit. Not a suit in the regular sense a suit, so no, it is not appropriate and should not be allowed as it does not meet the requisite dress code.So what about he Santa suit
Just to humor you and explain why.
Santa's red baggy pants cannot be described as dress pants or slacks, nor jeans.
Santa wears a hat, and hats are requested to not be worn. (he could take his hat off, but that would not be in keeping with his attire that he likes to promote.)
Since santa has such a large and bushy beard, I guess it would be hard to tell if he is wearing a collared shirt.
