To Polka, Or Not To Polka?

I'm in the process of doing our bedroom over. So far, I've painted the walls a shade of burnt orange. A new Sears sale came in the mail yesterday. While flipping through, I found this duvet cover. I think it's fun and funky. Instead of going with a "formal" bedroom, why not go fun? Plus it has orange polka dots on it, which I think will pop against the orange wall. Any thoughts?
