Re: Aikido Uniform: Part tradition; part discipline -
I attended an open house at a new karate school a few years ago and the Dojo Cho changed uniforms several times during the day, each time selecting a new color and fabric. His Shihan did the same thing with lots of satin, piping, reds and yellows. It didn't ring my bell at all, but they operate a very successful school, with tons of students and great tournament success.
My son runs a BJJ school and he and his students look like NASCAR drivers. Again, lots of students and success.
I still like a nice white gi!
