I have one, Dan, and though it is not really ichy, you might want to wear a regular undershirt under it.

Here's how I got mine. My mother and step father lived in Dublin, Ireland for a few years back in the nineties. That's where my step father got it. He's a little bigger now, but he also... ran it through the washer and dryer last year. Normaly it would have arms that are several inches too long, but fit me otherwise; I have several of his suit jackets. It shrunk to the point where it is a fine lenth for the kilt and the arms are just right. It is gray and cream colored.
