You ever see a Halloween costume that is SO awful, it transcends that status and becomes its own work of art? I have, and it is amazing. A costume that is so bad it is awesome can sometimes be better than a costume that is just plain awesome. Does that make sense? Just look at the Homer Simpson above as a perfect example of this ideology. It is awful, it is terrifying, but if you were at a Halloween party with that and went home, that would be the costume would you be most likely to remember still, days later. That says something. Good or bad, I'm not sure, but it says something.
So if you take as much pleasure in Halloween faux-pas as I do, this list of 13 Halloween Costumes That Fail So Hard They Win will be right up your alley. You have to give these people credit for trying. Not a lot of credit, mind you, but at least some. D for effort seems fair.
