Sorry,, Taylor’s book came out in 1961. Time flies when you’re having fun.
I have that same picture demonstrating the use of a belted plaid in an old book on tartans from the late 50s or early 60s.
In 1967 I was a competitive Highland Dancer. Girls still wore kilts in those days, the "Flora MacDonald" outfit didn't come in until later, unless you were dancing the Lilt.
