I kind of have this tradition of going to a nice restaurant the night before Halloween, in down town San Jose, in full dress, with a group of friends or a beloved some one. last year we all went in high renaissance ball gowns and armor and the like, year before it was animal themed cat bunny mouse fox wolf tiger... so on.
same restaurant normally but not allays, "The Old Spaghetti Factory".
Anyhow, diner plains set a side, we have yet to come up with this years them, but the groups larger this year so we might all just dress diffract, in this case I am going as a gypsy and my date will likely dress to mach.
However i think a Gothic or vampire them might be in the works...
