Halloween // Ideas for group costume 10 people

Hello! Hope its ok to post here ☺️ We are a group of 10 people going to a big event, where we need to wear a group costume. They call the theme "Fairytale" but it can be from movies, tv shows, cartoons ++

We are travelling, so should be able to fit in a suitcase, and not to complicated as we have around one hour to change.

Thanks!
