Jock, you are certainly right. This image shows a very high style band uniform, rather than something a typical highland gent might wear on a given day. I am surprised at how focused the labels are on odd specifics of the uniform rather than more useful info on standard elements like the kilt, sporran, and hose.

But when I was a wee lad of 10, this and a copy of a book illustrating clan tartans were all the resources on kilting I had available to me. We didn't have Xmarks in those "primitive" pre-internet days
