I may be wrong here, but the only people in kilts required to go regimental, are, wait for it.... Regimentals (and I think only then on specific occasions)!!

There is no rule for a civilian to forego undergarments. There is a thread over at ViperPiper's Bagpipe pages concerning this very topic.

From what I can gather, this woman is in the smallest of minorities. From the opinions I have read, most people at Highland Games and other functions would prefer men do not go regimental...

You did well to hold your tongue... Guid on you lad.....
