Can you wear a mandarin collar shirt, with a non-mandarin collar tuxedo?

(yes, I know that you probably clicked on this thread to yell at me, but please don't =)

I have a fly-front tux, and want to wear it. Yes, I want to be fashion-forward, because, I'm going to such an event. I just wanted to know if mandarin-collared shirts were only for the tuxedos of the same name.

Thanks in advance!
