I picked up two from some guy on Ebay who had had them custom made, one in a nice rich brown (a bit dark than "camel" I think), and a grey glenplaid. I get a lot of wear out of the brown, basically wear it as a blazer, usually with a blue shirt, sometimes a tie. I'm actually a professor, so the "professor look" is fine.

I'm only 28, but the cut is pretty good so it doesn't feel old to me.
