I wear the Urquhart Ancient Tartan when I am at an event that demands I show Clan Allegiance, I also Have a kilt in the Scottish Heritage tartan, because I love the new purple based tartans.
I also have a Lion Rampant kilt, pleated to the stripe at the back, I love wearing that one too. I wear it to display I am a Scottish Monarchist, probably what would be termed a Jacobite in the old days.
I have had adverse comments from 'purists' here in my native Scotland, who view anything that is not based on a pure tartan is a skirt. Its all down to point of view I think, its definitely a generational thing I believe
I have had an elderly gentleman ask me if I didn't know I shouldn't wear a tartan tie with a kilt, the rule being no tartan above the waist with a kilt.
Another thing I love to do, is wear black hose with the Purple kilt, as I think they look great with it - however, that got another purist on my back at Braemar games, when I was asked if I knew that black hose should only be worn at funerals.
Ah well, I always thought I was a bit of a purist when it came to kilt wearing, but believe me, there are people out there who are so straight laced about these things its scarey....
