There's a security guard.

Jessica's brain froze everything as the burly male security guard eyed her from head, to her well endowed chest, to her smoothly shaven mound, and finally down her thick legs and bare toes. In his hand was the remains of her thong. After finally screaming internally long enough she wrapped her arms around herself.

"And just what are you doing?" The guard boomed causing Jessica to quiver. "I lost my clothes...could you hel-" "Oh sure, you weren't streaking the school huh?" "No! Please you don't understand, the elevator ate my dress." "Ok that is enough"

The security guard reached behind back and produced a set of hand cuffs. "Don't make this harder than it has to be." She couldn't risk not being able to cover up,but she also reasoned maybe if she went with him he would go easy on her.
