For Track or Treat children are allowed to wear costumes to school. However, they MUST be able to use the bathroom and redress by themselves. We still have a school day, and we can't spend all day in the bathroom. No masks or accessories are allowed. Too many times in the past an important costume piece has been lost at school, and then we have a sad kiddo. I always urge parents to not send students to school in a special costume, but maybe a simple dress-up one.
