Men do not worry about matching clothes or whether anyone else wears their tuxedo, because just about everyone else is wearing the same style. Sure, a couple of variations to the standard tux do exist. But when you boil it down, if the tux fits, we wear it. Maybe tux designers think guys are just too boring to want anything different. I like to look at it a different way.
Guys are practical.
Use the rest of the time to watch a baseball game. I suppose it might be exciting to alternate bow ties and cummerbunds every once in a while. Deep down inside all of us something makes us want to get dressed up. Unlike the primal urge to remove our clothing and streak the Lawn, an aristocratic urge makes us want to put on as much clothing as we can and dance the Virginia Reel. Of course, champagne helps to top off the evening and adds greatly to the enjoyment.
