Re: Wearing of Hakama at Seminars
I'd skip it, personally. Etiquette aside, as mentioned above, if you are wearing a hakama, people expect certain things. Not so much technique and style on your part, but rather the ability to take bone-jarring ukemi, that "special" yonkyo they've spent years developing, or full-bore atemi.
IMO, a little protective coloration is not necessarily a bad thing.
