I consider myself blessed with a wife who supports anything I do. She has had nothing but good things to say about my kilts. But then again, she was kind of a rebel in the fashion department when we were in high school. One of the many things I liked about her. We have tried to pass these values on to our boys, you know, not living your life worrying about what others think of you. I'm sure that is what is bothering your wives, not that they don't like it.
We must have been somewhat successful in teaching, because my 15 yo son wore his kilt on the first day school this year. It is a little on the 'goth' side, but still took some guts on his part.
