OK, every year for the past four or five, I've dressed as Harry Potter for Halloween. And for school, I'll probably do the same thing again this year. It was kind of a no-brainer costume for us. I mean, Joe has long black robes for commencement, anyway. Mom knitted us a red and gold scarf, we bought a red and gold striped tie. I wear my glasses instead of contacts. A little lip liner scar later ... et voila!
Anyway, we're going to our friends' house for a Halloween party following trick-or-treating and I don't want to wear the same costume I wore last year (the Harry Potter). I also don't want to go out and buy or rent a costume. I like to make them myself, preferably at minimal cost and sewing effort (though I am willing to spend some and/or sew some).
Joe went last year as Agent Smith (though people not inaccurately guessed "Secret Service Agent" and "Man in Black). I don't know if he'll do the same thing this year.
Emily is going as a rather complicated robot (not using the red wig at all, so I guess I could). And Matthew is going to be a prince (a selection largely made on the basis of being allowed to carry a sword). So we won't be going for a "family theme" costume.
Quick update: one convoluted phone call later ... Joe is going to wear his tux and go as the Phantom of the Opera.
