OK, bear with me. As my trip to Scotland gets closer I keep coming up with new questions. This probably won't be the last. I promise I'll always do a thorough search of previous threads before posting!

So here's the question of the day. (I apologize if this seems to be a frivolous post.)

I'll be there in December, so I'm not even considering taking light-weight kilts. I have two 8-yarders with enough wool to keep my tush from freezing... MacDonald modern (that will hopefully arrive next week!) and Black Watch. The MacDonald is a given, especially since I'll be in MacDonald country (driving down the Great Glen to Invergarry) and I'm a "card-carrying" member of Clan Donald USA . But what about the Black Watch? I don't want to appear that I'm impersonating a member of the British military, or worse that I'm dishonoring them. Around here when the temperatures dip I usually wear the BW with my black commando sweater. How would this be perceived? Would my favorite black hooded sweatshirt be a better choice?

An analogous situation might be the wearing of "army surplus" clothing here in the states (and probably everywhere), which has been popular for decades. Most folks, including veterans and active military, probably aren't alarmed or insulted by this. There is, after all, a clear and easily perceived difference between a civilian wearing a military surplus coat with jeans on the one hand and donning a full uniform on the other. Would it be the same in the UK?

And I am aware that the Black Watch tartan is also used by several clans and associations, and I have seen the old thread about wearing BW in Ireland.

So what say you experienced travelers, and you native Scots. Do I wear it or leave it at home?
