Well, GHenry, thanks for your candour.
It does seem as if you might have difficulties fitting into your inherited kilt.
Perhaps it’s time to get yourself one made to measure.
Since you’re in Wales, you might like to experiment with a Welsh tartan. But a Scottish tartan would be just as appropriate.
And have a look around here – there are all sorts of ways to wear the kilt.
The sporran is compulsory for men (but it can be a plain leather pouch). However the rest of the outfit is optional.
Perhaps the X Marks experience will give you a different outlook on tartan (wool or other materials).
Regards,
Mike
