They wore the same as other UK countries did at that time.
Kilts
They wore kilts and tarps.
Scottish people sometimes wear the kilt at weddings and other special occassions.
they didn't. that is scottish. or maybe irish!? or both.
the best of them do. i'd say 1%.
There isn't a Scottish King.
Very few Irish People wear kilts, it is really a modern Scottish phenomena. The only people to wear kilts are pipe bands etc.
in the3 60's and 70's people wore triangles and squares and bright colors
Scottish people wear tartan patterned clothing.
None, except for special occasions, this is the 21st century!!!
Rich people in the 1960s would wear very elaborate and expensive clothing. This clothing would have fur and occasionally high-quality silks.
The Scottish hate the Irish, so they wear their normal clothes and don't celebrate the holiday.
