No.
If you want to dress up like a circus worker...
Join the circus.
However, you know what, if you can find some simple Holiday colored prep-tie, and you can pull it off without looking like a tool - well done. However, considering most of the middle aged clowns out there are wearing some stupid Ornament, Stocking, Candy-Cane abomination that it is just embarrassing to see a professional running around like a circus worker. A cheesy Christmas tie is still cheesy, regardless of where it is worn - the Airport, the Office, or a Cockpit.
Yeah, I'm the Grinch.
