Two Telling comments? The Answer Perhaps?

In each case, and that is by 8 resident Scots, I was told, very strongly, that White Hose with Ghillie Brogues, Prince Charlie with vest and Dirk Belt, Ruche Tie, and White Rabbit dress sporrans were the preferred manner of dress in Scotland for all events, even a beach wedding as these were.

I spent the last two weeks in Scotland. I saw kilts worn at convocation at University of Stirling and at three weddings in Nairn. All were during the day and all were pretty much dressed as described above (the main exceptions being black bow ties instead of ruche ties and black shoes instead of gillie brogues in some cases).
