Gym class

Gym class! That would be Jessica's savior. She could wear her PE kit all day. Sure, it'll be sweaty and smelly after gym, but it won't be attending school naked all day. She walks up to the PE office when an assistant comes out and says "Oh my gosh! This isn't the locker room, honey! They're over here!"

Jess tries to speal but the assistant interrupts "Don't worry, honey, you aren't in trouble. I know the layout is confusing. Over the summer they plan to fix it. You aren't the first one to wander out. Well, you're the first to walk out here totally naked, but that's okay. I'm the only one that saw you". If only she knew. The assistant continues "There, I unlocked it for you. Hurry up and get dressed or you'll be late.".

The temptation to just stay in the locker room all day arose in Jess but she's never missed a class in her life and the idea of skipping class seems worse than even going naked. Maybe she can find clothes to steal in the locker room.
