I work at one of the seemingly ubequitous 3-letter agencies (CIA, NSA, NRO, etc) in the intelligence community around Washington DC. Unfortunately, my company (yes, I'm a government consultant), insists on a jacket, and tie at work. No, they won't accept an argyle and a kilt, they just barely tolerant a sports coat and slacks instead of a suit. I have a picture of my wife and I at the Marine Corps Ball last year in my office. Of course I'm in my Tewksbury Leatherneck. The director of our division, a "C" level agency employee, Presidential appointee, confirmed by the Senate, walks by and stops. "Hey, nice outfit!" he says, pointing at the pic on the wall. "I like it" I say, "But my company won't let me wear it to work."
"Neither will mine, I should bring some pictures from Grandfather Mountain to show you my kit."

We chatted for a bit. He's also a Marine (ever notice how many kilt wearers in the US are Marines?). We're both going to wear our kilts to work next Tartan Day.
