There's an ad for a lightweight wool kilt in Edinburgh , on Gumtree. It's a Menzies (black and white) tartan, 36-38" waist, and the asking price is 15 GBP.
Unfortunately for me, I found out from the seller that it's 28" long. That's too long for me, but perhaps just what somebody out there needs.
Here's the link:
