I know there are few concrete answers to these kinds of questions, but I'm curious of everyone's opinion on this. I'm not a fan of the fly plaid (to those of you who are, more power to you, just not my thing) but a piper's plaid or a drummer's plaid is more my style (especially the latter since I'm a drummer!) is it considered improper to wear one of these with an Argyll jacket? I know it's not something I'd do very often, maybe just for very formal occasions. I've seen someone with this before and it looked great! I've read it's sort of against the rules though, as it were.
