I came across this photo, of a pipe band back in the day.

Posing with the band is this gent in civilian dress of the period (when wearing long hair sporrans with tweed was the rule rather than the exception) but what stood out to me was that his Argyll jacket has breast pockets.

I did a search of this forum and couldn't find any thread on this topic (at least with "breast pockets" in the thread title). But I seem to recall photos of... who was it? perhaps a Chief? wearing just such a jacket in lovely windowpane tweed.
