After entering, she realized her bra was all she had on

(chapter originally by Phantom Pen on writing.com)

Chihiro felt a surge of relief as the council room door opened, slipping in and slamming it shut behind her before leaning against it to catch her breath. That had been far too close. The sound of footsteps and conversation passing by the door made it very apparent that one second later and she'd have been seen. Thankful that she had avoided such embarrassment, Chihiro slid down the door, coming to rest on the floor.

The feeling of cold tile on her bare skin made Chihiro's eyes snap wide open. That wasn't right. Looking down, Chihiro gasped as she saw the entirety of her pelvis, a tuft of brown hair being the only thing even resembling cover on her lower half. Taking her hands off her hips must have been all her makeshift skirt needed to slip right off! Even worse, it was nowhere to be found! It must have fallen off in the hallway. The hallway now filled with students. All Chihiro had left was her bra!

"This can't be real..." Chihiro muttered deliriously. This was too much to comprehend. She was sitting in the student council room, a place she saw regularly, with nothing to her name but a plain white bra. The only other clothing she had left was somewhere out in the hall, and that was assuming a curious student didn't pick it up. What on earth was she supposed to do now?!

Chihiro knew she couldn't go into the hallway now. There were too many people. The skirt was a loss... Chihiro would have to make do with what she could find in this room.

She knew her odds were slim, and even if she found something, it'd likely be dubious at best, and not at all inconspicuous. Still, resigned to the need to find something, Chihiro began methodically searching the room.
