I vote BUY as well. You'd be surprised the use you get out of it. I wear mine at Christmas parties, and it's the talk of the party. I found two at a goodwill years back. A modern After Six that was $100 and an OLD, wool formal tux, ala Groucho Marx, with tails for $55. The old one with the tails is an absolute hoot.

Really helps with ones Groucho imitations.
