I've done a few plays, but I've never been much of a costume person. Never went that route at conventions, but wow it was kind of a blast doing it for charity.
Found I was freaking out a few folks, however.
My back story was that I was sort of a Cthulhu-conjuring sorcerer like Dean Stockwell in The Dunwich Horror. It's an old movie but you get the picture, a nice fantasy dark sorcerer, generally harmless.
I couldn't find a copy of the Necronomicon to carry, but maybe that was for the best.
Cthulhu lies sleeping
"The problem," said Christine who went in Renaissance dress, is that nobody but you knows who Cthulhu is."
"Apparently not the old guy who's staring at me disapprovingly," I said.
This was in a restaurant, and he was sitting, head propped on one hand, glaring. I wanted to say: "Hey, there's a pimp over there. You're not staring at him."
Purple suit and fur hat, cane. No, no problem with a pimp, but a sorcerer?
Got a gasp from one waitress. "That's not a pentagram is it?"
The packaging said amulet. Note to self for next time, spring five dollars for the jeweled ankh.
"I think it's a pentacle," I said.
Not that that would really be any better in her mind, I guess, but hey if you can't dazzel 'em with brilliance... (Actually my friend, Earl, noted it's a six-pointed star if you look, so it's not a penta anything.)
"Just quit talking to her," Christine said.
Why, I was thinking, is a sorcerer costume such a big deal? It is just a costume at a costume party. If I'd come as the Headless Horseman it would be reasonable to assume I still had a head sequestered somewhere on my person.
One waiter actually was pretty cool.
"Can I get you anything else?" he asked. "Salt? Pepper? Holy water?"
"There's a pimp over there," I said.
It's good to try new things, but costuming is an adventure.
