A comment..apropos of nothing specifically but maybe worth considering...

For non-traditional kilt wearers "Do's and Don'ts'' are almost meaningless. That's not too surprising when you consider that a "non-traditional" kilt can be anything from a mid-thigh scrap of tartan to a wrap of leather billets.

If you wear the kilt to honour traditions and ancestry and so forth, then by its very nature you're going to be constrained by "rules" and expectations. Most who wear the kilt for these reasons, willingly...even joyously...embrace those traditions and those rules.

As a thread, "Do's and Don'ts" only makes sense if there is a standard of "appropriateness" that is recognized and accepted as the founding principle.
