The box could have been nondescript but in fact, it wasn't. It was decorated with black silhouetted characters against a maroon background that represented clear depictions of fairytales: the Little Riding Hood and the big bad wolf, Rapunzel and her long braid from the window of her tower, the Little Mermaid under waves, Cinderella loosing her shoe and looking backwards, Snow White about to eat her poisoned apple, a princess about to kiss a tiny frog with a crown upon its head,... These were rather elaborate, the box velvet and there were pictures of tales that you had never heard of before. This was really an object of sophisticated workmanship and you expected the costumes to be just as elaborate. You had not assume as much, to be honest. You had thought that everything would be... well... cheap. But as you looked around the shop, you could guess that everything was of rather high quality. The costumes here were pretty refined.

With reason. You walked back to your high school, wondering which costume you'd be within soon. Your apprehension did fade a little, as you now knew the costumes should be rather dashing and stylish. You pondered which fairytale character you might be for the night.
As for the lady, she was very happy to have rented the box of costumes. This was not an out-of-place costume. She was a genuine witch and she was in contact with many realms or other worlds. These costumes would transform the wearers and soon they would be sucked into a new world, their new home. Soon the fay realm would be welcoming new citizens...
