I notice that most of the pics around with guys wearing PC's don't have them with a fly plaid, anyway. Pipers wear plaids, and I suppose if I went to a Saint Andrews event I might want one, but to the symphony or other formal events that I got to, the plaid would just be a hassle.

I really like the military mess jacket look with a kilt, actually. the Eton jacket is, basically that same look.
