That's verra niiice!
I especially like the wetern look. You need a holster with a Colt 45 inside it.
I think I'd wear my new hose with the cowboy boots, pulled up to the right height and tied with Professor Newsome's garters. If you wear a coat with it, though, you'll have to have it tailored to the right length and so forth.
Congrats on the new kit. It all looks very sharp!
