The thrifty and non-crafty parent's guide to successful Halloween costumes - Ninja edition
Ingredients, black sweat pants (outgrown, but still workable), black shirt, black socks (mine, so that no bare leg shows), black shoes, black gloves (worn backwards so that the gray 8 bit skulls don't show), my black fancy scarf (held on with the help of some black hairpins).
Not one new purchase for this costume. Not. One. According to MM and Mr. Spock, his costume went over very well.
