Weaver, there ARE non-bifurcated Welsh male garments. Apparently it's "cilt" in Wales. Be careful typing that. Most will argue that the Welsh cilt is a result of the English Victorian "Scottish Revival" in the 19th century, and not a historical Welsh manner of dress. Same might be said of the Irish wearing kilts. Strictly speaking, in Scotland the kilt is a garment of the Highlands. True Highlanders have some special terms that are applied to Lowlanders and English who don kilts. The kilt has become so ubiquitous that tartans have been created for the American centennial, and the US Marines even have a tartan. So some guy named Johannson or Chavez can wear tartan--if he's a Marine. I once ran into a guy at a Highland games who said he was from the Highlands of West Virginia and a member of Clan McRowdy. The dress tartan was blue denim and the hunting tartan was Marine corps camo.
So wear what you darn well please, I reckon. I'm about a quarter Scot, and you won't offend me a bit. Well, unless you start talking Brexit.

Welsh Kilts Welsh CiltsAnd for the historians, this little Wikipedia piece is interesting. There is no documentation for kilts in Scotland before something like 1690. Also, the modern kilt as we know it, was invented by an Englishman. The Scots adopted it after one clan chieftan aparently saw the advantage of the "skirt" being a separate garment. It quickly spread across Scotland. Strictly speaking, all those kilts at "Rennaissance Faires" are a complete fiction, as is virtually all the SCA stuff.

Kilt - WikipediaA little aside concerning the kilt pin. The story goes that Queen Victoria was reviewing troops, including Highland regiments. Apparently it was a windy day, and a kilt or five was lifted. The Queen was shocked. SHOCKED. She ordered that a pin was to be worn on the apron of regimental kilts. The Highlanders were horrified. HORRIFIED. They were proud of the swing of their kilts. A clever Scot determined that they could comply with the order and maintain their tradition by attaching the pin to the apron but NOT pinning it down to the underlying fabric. Love the creative Scots' defiance.
