McTag, I've seen some sites on the web that say that some wear underwear under their kilts and others don't. I don't know who to believe. What is true?
I think you can believe what you want.
I have heard that it is not "traditional" to wear anything under the kilt, and I dare say that tradition holds good in the armed forces.
However I know that it must be difficult for the poor privates (like that one, eh, milord Ellpus?) on New Year's Day parades in freezing temperatures.
Otherwise, I'm sure other wearers of the kilt will make their minds up individually about whether to "go commando" or not.
And I'll finish with an old chestnut:
A young lady goes up to a kilted old Scottish soldier, and asks
"Tell me sir, is anything worn under the kilt?"
To which he replies
"Nay, lassie, it's as good as everrr it was"
