Thanks for the links! I've thought it over more, and I'm leaning towards the tux. I wouldn't wear it to someone else's daytime wedding (or any other daytime event, for that matter). I think a suit could look great too, but my fiancee seems to have her heart set on me wearing a tux, and I'm probably never going to have another excuse to buy one. It's something I can see myself enjoying on one or two occasions a year for quite some time (assuming I can stay in half decent shape).
