UPDATE 2023-08-141: Clan.com now lists McCandlish tartans (all of them, even in three “modern”, “ancient”, and “reproduction” colour palettes each) as available to order directly, either as cloth or as kilts and other clothing. It is not actually kept in stock, so it is a custom weave (through D.C. Dalgliesh who are now owned by Clan.com AKA Scotweb). It is not dirt-cheap, but at about US$1,027 for an 8-yard kilt (probably plus tax and shipping) it is actually the most cost-effective way to get a McCandlish kilt as of 2023. (On average, a proper kilt of this sort in non-custom tartan is around $450–$800 depending on vendor. Poly-viscose “sport” kilts are much cheaper, but I have yet to find any vendor that will produce McC tartan in that material, short of ordering a full bolt of it – 40 to 100 yards – at great expense.)
