The dice landed on green, which meant you had no other choice, but to wear the green dress that came with the red hood cape, meant to represent Red Riding Hood from that famous fairy tale you use to read as a kid. You also saw that there was a picnic basket next to the dress with a checkerboard blanket inside it.
You take off your clothes as you needed to get the dress, and essentials on, while at the same time, you place the clothes you were wearing in the picnic basket, so you won't be able to lose them during the masquerade dance that night. However, despite the fact that the outfit was loose, and tight at the same, you began to see trees, and bushes come out of the floor, while the changing room stalls disappear, and the floor itself gets replaced by the grass, and dirt from outside the school.
