Thank you for this insight, OCRichard. I have often pondered a Glengarry but always felt that it looked too martial for a me, a civilian, and ruled it out. Now, having learned a little bit about the origins of the Glengarry as a civilian bonnet I might revisit the notion down the line.

My favourite headgear is (by far) my fore-and-aft. I don't wear it every day but I do wear it kilted OR trousered (it gets little use now that the mercury has risen a lot).
