OK, you're asking a bunch of gunnies for fashion advice.
Folks who debate the appropriateness of wearing camo to the range.
People who think Hoppes No 9 is not just a solvent, but an aftershave. (Actually, I prefer CLP for that job--jfruser)
Given the above, you are a brave man, indeed.
I have no advice. See, I'm married and let my wife haunt the discount racks for my casual clothes and I go to Eddie Bauer for work clothes once every year or two and buy Khakis that fit---one pair of EVERY color.
