I did a quick search but couldn't find what I was looking for.

I'm headed to the Triad Highland Games tomorrow and (obviously) planning to wear my kilt. Thing is, it's about an hour and a half drive to get there. I have driven around locally while kilted, but have not gone any distance yet. Would I be better off throwing on a pair of board-shorts or something for the drive and kilting up when I get there to avoid wrinkling (and sweating, eew) up the kilt?
