I think it is pretty obvious that if a full blown 8 yard tartan traditional kilt is like a pair of formal tuxedo slacks, then the utilikilt type "MUG" is the chain wrapped, studded cargo pants. I think you ought to wear one accordingly. Out in the woods, in a workshop, at a concert? Sure. To a formal event, no way. But as a way of gaining additional kilt acceptance and bringing in younger kilt wearers I think the MUG is invaluable.
