I don't know that there is such a huge difference.

If most people over here wore a doublet and most people over there wore a PC you could then state that there was. I don't think I have seen any pictures of UK or even European X markers wearing a doublet, apart from Hamish.

My experience is no difference to McMurdo's in fact he has probably seen more doublets in real life than I have!

How about a straw poll - X markers saying what the own as their most formal wear?

I'll start - mine is a PC. I would love to own a Montrose also though!
