Hey, I actually know the two guys on the left, though I've never seen the one on the right. I think his all-tartan outfit looks sharp! I'm not saying everyone can pull it off, but he does.

I've never seen a tartan PC jacket before, but I have seen tartan Montrose doublets and Sherrifmuir jackets, and these look smashing. Very elegant. Defintely should be reserved for the most formal of occasions. But Todd is correct, there is definitely historic prescident for it.

Oh, and Dread, there is nothing that says not to wear a belt with a PC jacket. It's the vest that determines whether or not to wear a belt. Any time you wear a vest, whether a PC vest or not, you would not want to wear a belt.

Aye,
Matt
