A mask

The only thing she could find was one rag. The only logical thing to make it into was a mask. There was only enough cloth to cover a small area, so it should be her face. There would be a stark naked girl wandering the hallways, but no one would be able to tell who she was. No more running and hiding, she could strut around confidently. People could take all the pictures they want, and she would not even care. It would be her own secret identity. She would be like Batgirl or something, if Batgirl had an exhibitionist fetish. It was actually kind of thrilling.
