Yes, you should wear a suit instead of just a santa hat.  We won't turn you away, but you will feel out of place.  Santa knows its been a down economy. He laid off over 300 elves last year, but still maintains the highest level of elf employmenet over Keebler and Wonka.  As such, when Santa finds a cheap suit, he wants to let you know about it. 

Early reports are that Walgreens has whole suits (coat, pants, hat and boot covers) for $15.  No doubt manufactured in China and lined with Lead, these cheap suits will be perfect for you drunk santas. 

So get to Walgreens and buy one.  Only 2 weeks left until Santarchy!
