I looked up cosplay online and found:
"The most specific anecdote about the origin of the word "cosplay" was that Nov Takahashi (from a Japanese studio called Studio Hard) coined the term "cosplay" as a contraction of the English-language words "costume play" while she was attending the 1984 Los Angeles Science Fiction Worldcon. He was so impressed by the hall and masquerade costuming there that he reported about it frequently in Japanese science fiction magazines. "
He He, I was there at Ratcon for three days, and was in a dam good Fett outfit (made by a friend who could not go) for all of Saturday. I remember several groups of Japanese fans who were taking photos of everybody in costume... I walked up behind one group and put my hands on their shoulders. A jump, a look, a jump back and then the the smiles. Lots of arm over shoulder photos and I got to be "Fett Sama"

I'd include a photo but have not paid my forum fee yet.

And in my youth, I was a Mod, not a hippie.
I guess I like clothing that is non-current.
I've never made it to Pensic, but in the wars out here I start with pike, shift to 7 1/2 foot cutting polearms, then to glave, then bastard hammer. I feel I need a caddy at times.
In WW the twice I do GI and pre side-change Italian.
