Yeah, it's late but what did you guys do? Still dress up? Trick-or-treat?
My English teacher actually gave out extra credit to people who dressed up xD So lame but, I cosplayed as Hatsune Miku from this video: Alice Human Sacrifice - Vocaloids
Yukihane was Meiko.
I was too embarrassed to go trick-or-treat at my age, so I stayed home and handed out candy xD; Though Austin (our Ovan at AnimeIowa) went trick-or-treating with his college friends because he's poor and wanted free candy.
