As a Scot by inclination, married to someone who may be able to claim ancestry
from the Border but certainly not the Highland, I am suprised that no one has
recommended the Black Watch, which, when clan-kilt-wearing was outlawed, was worn
by Highland regiments who fought for the British in what is known in the US
as the French and Indian war (1750's). Among re-enactors who enjoy spending their
weekends outfitted correctly in the clothing and equipment from the period, it is
the only permissible kilt and seen quite alot.
