I think tweed kilts are traditional, but quite rare. I'v seen one man in Scotland wearing one, Herr Bruno Schroder.

I have a photo of my grandmother and her brothers and sister and cousins with their grandfather Sir Sandford Fleming, in which one or two of the boys are wearing tweed kilts.

I am considering having a kilt made up in Harris tweed, but it would be in MacLean tartan. That Stephenson kilt made by Matt Newsome is wonderful!
