Thanks Graham for sharing your experience traveling in a kilt. I had wondered how flying kilted might turn out.
A recent experience traveling in a car makes me think I won't wear a kilt while flying. I drove home kilted (Stillwater Standard) from a business trip. I was in the car about 3 hours. I couldn't believe how wrinkled the pleats were after the drive home. I imagine sitting in an airplane seat would have a similar effect.
