This is the costume I wore in Kindergarten. Note how it says, "With ventilated mask." Did the early mask have no breathing holes?
And in 1st grade I went as the devil. I remember being embarrassed because the smock portion of the costume showed the devil holding a pitchfork and I remember saying to my mom, "But if the devil has hands and I have hands it means that the devil has four hands! That doesn't make sense!" So I remember holding my candy bag over my chest when I went to doors so people wouldn't see the extra hands.
