I went through the same thing! I wore my kilt to prom and had to get the principal's approval-it was not problem since it is a heritage issue and I wore my evening wear in advance one day to show him what it would look like. Of course, I was asked what would be worn underneath and naturally I said a pair of gym shorts of course! Well, that's what he wanted to hear-I wore it regimental to prom-keeping my ancestors pleased-as well as my prom date! HA!
