I sewed my Sally costume from scratch, sewed Jack's out of an old pair of pajamas, and the Zero mask is made of card stock; making the costumes totaled to probably almost 12 hours of work or more. Our hair and makeup took another 3 hours before we were ready to go out. It was worth it.
Unfortunately our pictures are grainy because we took them outside in the dark, but you get the idea:
Hope you had a happy halloween!
