Question about fly plaids. I want to get one to match my Red Ross kilt but am curious about how they are supposed to look. The ones seen on eBay and other supply websites seem to be a square of tartan cloth, fringed and bunched at one corner to take a brooch on the shoulder.

However, in Thompson's book, "So You're Going to Wear the Kilt," he describes a plaid (evening plaid) as " a rectangle of tartan, pleated at one end, that attaches to the waist with a belt or tape. The other three sides are fringed like the ends of a piper's [drummer's] plaid, and there is a knot of fringe midway of the end opposite the pleated end [for the shoulder brooch]." 3rd ed., p. 81

Can someone please explain why I have never seen this design advertised and why the people at such a reputed Highland source as Kinloch Anderson have never heard of it?

Thoughts?
