Quick Solicitation

I promise, I'm currently writing a post about my trip to Tennessee. But for the nonce, I'm soliciting advice. Another wedding to go to this weekend. Do I wear:

A. The more traditional gray two piece (slight herringbone pattern)

Or

B. The charcoal pinstripe three piece that makes me look vaguely like either a mobster or a fat cat from the 20s?

Poor quality pictures below.

And, just as importantly, what color shirt works?
