My 15 year old son owns 2 kilts.

He's also a black belt in American Freestyle Martial Arts. He's 6'2". Nobody is going to bother him, he's simply too tall.

We have several young men in kilts at church. Prester John's 2 boys both wear kilts, and another kilted gent has a son with a passion for one. Another family is currently awaiting Grandma's production of three kilts for boys ages 11, 7 and 5. She's using the Ethnic Folkwear pattern to make them each one with a plaid fabric purchased locally in time for the Kirkin' o'the Tartans.

Considering the preteen jonesing going on at church, I don't think that these boys will have much of a problem once they get their kilts. They all are too excited about having them, and if anyone disses them, I expect it will be ignored.

I had expected a lot of teasing for my son, but none has developed that I've been told about. Prester John's boys seem to have no problems that I've heard about.

Long-winded to say: don't worry about it. Make sure your son wears a sporran and knows not to draw a weapon in a fight, should you give him a letter opener or an pint-sized knife. And post pics!
