I hesitated before writing : " the essence of traditional costumes is that
everyone be dressed
as I have obviously not been all round the world, but my limited experience
is just that. They are a uniform, evolving, but leveling. Unlike the
costumes of traveling dem groups that need to add variety and colour to
please their audiences. Richard's expeerience is different from mine.
I would also add that those "Scots" that wear the kilt have also turned the
national garment into something like a folk costume by insisting that it
must be worn with certain standardized jackets and accessories. At least the
rugby fans wear their kilts with everyday sweaters & t-shirts, just as they
would if wearing two-legged garments.
(If you are wondering what is the difference between Scots and "Scots", let
me say Richard would probably have used the word "wannabe". I have a
feeling that, across the Atlantic, they are fussier about detail than we are
on the eastern side)
