quick and easy Halloween costume ideas

I'm not entirely convinced that I'm doing anything for Halloween this year, though if I do, I plan on going as the Utz potato chip girl:

For a former costume designer, not particularly impressive, but no one in San Francisco needs to know/cares. Also, it's in keeping with my apparent total aversion to all costumes pop-culture related.
