I know Denver's on the Eastern slope, but they consider themselves Western. You might be the only guy in the city with a tie on?

Open neck shirts are common in our Western heat...unless your church is a very formal one consider losing the tie.

Mostly undertakers and attorneys headed for court wear neckties in the summer in the Western U.S.

I agree with a shirt that compliments the tartan too.

But hey Graham...I can't see ANY garments overriding the core of who you are...just smile and they'll hardly notice what you're wearing.

Enjoy your time in Denver. Hope they get you off the plains and up into the Rockies while you're there.
