I agree with Jun and Mikey but I have one question. What if I were to visit a dojo where everyone wears a hakama but did not own a hakama. Would this cause any problems?
I don't own one and wouldn't really know how to put one on. I'm also not likely to buy one soon as I am only 5th kyu and only yudansha wear hakama where I train (which puts off the purchase for several years at best unless I decide to start iaido).
It would be hard to do as the romans do without the needed gear.
