It is well known that George IV visited Edinburgh in 1822 and affected a fanciful highland dress for the occasion.
However, I found that Louis made one for him in 1789.

Sure enough there was a newspaper report:
From the Caledonian Mercury, Edinburgh, 18th June, 1789: “The Prince of Wales, and the Dukes of York and Clarence, have provided themselves with complete Highland Dresses…. The tartan plaid, philebeg, purse, and other appendages, were of the handsomest kind…”
I also understand that the highland dresses were worn at balls celebrating (genuinely or otherwise) the King’s recovery from his first bout of ‘madness’ in 1789. This had put paid to any hopes of a regency at the time.
I don’t know who made the outfits for the dukes, but it doesn’t seem to have been Louis.
I can imagine the long-suffering tailor pursing his lips and exclaiming:
“Sacre bleu! Where am I going to find 71 yards of SILK plaid?”
