Are you hoping to just buy all costume elements and accessories, or are you willing and able to do your own sewing, papier-mache, spray painting, etc.? What’s your budget?
Is this just you or will you be enjoying the festivities with a friend or partner, who might collaborate with you re. costuming? Will you be throwing a party, attending a party or two, or just answering the door to the neighborhood rugrats and juvie delinquents of the night?
Do you foresee any climate-related restrictions (i.e., very cold temps vs. an immodest fairy costume, or likely rain)?
Do you prefer the old standbys, or are you game to consider current political or pop-culture references?
Tell us a bit about you: gender, sexual orientation (and camp-friendliness), sexual modesty (again, many costumes can get a bit racy or revealing), body type (height, weight, even race)…?
