Kilts are great, 'M'. A proper one is made of 27yds of material which is why very little (or nothing) is worn underneath. I have a nice one and yes, I have put it to good use on more than one occasion!
I fucked a guy in a kilt once. It was at a wedding and most of the guys were wearing one. My boyfriend was off somewhere talking football or something just as boring. I got hold of a guy and we had a shag in one of the toilet cubicles. I was pretty pissed so don't remember much. I did remember to check for spunk stains before returning to the party.
