Wear your kilt, travel in your kilt (trust me it is really comfortable), leave your trousers at home. Sure you will stand out, but if you are not bothered, no one else will be. If you don't and you do happen to chance upon someone else wearing a kilt, won't you feel a little envious? Chances are that is how some may feel if you are wearing yours.

It is not customary day wear in Scotland, last time I was there, I was the only one I encountered, even in kilt sales shops. True I don't have an American accent, but for the most part my Scottish accent is not very obvious and, by those who speak to you, you will be regarded as a tourist whatever you wear.
