The issue is that this person I know start teaching Aikido but sometimes he goes dressed as a Ninja; sometimes he wears dogi of such colourful designs!!! Now a good number of his young students are wearing whatever they want to practice. I talk to him trying to make my point on tradition and discipline. He took it well but still wears what he wants.
Any parent that has or has had kids will tell you that tradition and discipline
does not attract kids. As a matter of fact that will drive them away.
It has to be fun to attract and keep kids.
