I have a friend that is a WWII buff and we sat and talked a lot about stuff like the war and the reasons behind it and you now it's all in the uniform. Once you're in it it usually does all the work for you.
Wearing a tuxedo isn't as simple as it sounds. I've been to a lot of award shows in Hollywood over the years and have seen some pretty sad tuxes. It's surprisingly easy to go off the rails.
