When I first started wearing the kilt I asked everbody I could about how to sit down when kilted. I felt like Jackie O at a tea party smoothing out my pleats everytime I sat, but sitting bare-assed on my friends furniture didn't seem like a great alternative. The Scotsmen I spoke to all agreed that you simply gotta pull the kilt tight as you sit down, preferably with one hand in a quick, sharp and unobtrusive motion...and I agree, if your pleats do happen to get discombobulated, well, so what? life is definately too short...
