Well; you see, it's a free country, and I can wear (or not) whatever I want, wherever and whenever I want. Simple, eh?
I enjoy wearing kilts, I also enjoy switching colors.
Even if my Ancestors were NOT Scots,- which they were, by the way- I'd still wear them.
I could've chosen a Muslim Burkha, or German Leiderhosen but found the Kilt more comfy. and practical.
