Trying to strip the girl was too risky. Isabel didn't like to think of what would happen if she lost that fight. Steeling herself, she took a deep breath, then tapped on the stall door from the inside. "Hey," she whispered. "Can you help me out?"
The girl turned around, a look of mild surprise on her face - she had obviously thought she was alone in the restroom. "What's up?" she asked, in an indifferent tone, squinting to try to get a look at Isabel through the crack in the door.
"Um." Isabel hesitated, but she was committed now. "I...kinda, um, kinda need some clothes here." She winced to hear herself say it aloud.
"Clothes?" The girl blinked, visibly nonplussed. "What do you mean you need clothes? Go buy some. It's a mall."
"No, I mean..." Isabel sighed. "I need clothes to wear right now. Because I...I don't really have any."
The girl was quiet for a moment, then realization - and faint amusement - dawned on her face. "You mean you're naked in there?"
"No!" Isabel felt goose bumps prick up along her exposed flesh at the very thought. "I...I still have underwear on!" Was it her imagination, or did the girl look disappointed? "But I had an accident, and I lost my dress, so I ran in here to hide." She swallowed. "Can you help me out? Please, I can't go back out there like this!"
"Oh." The brunette girl paused. "Well, let me get a look at you first."
"What?"
"You heard me." The brunette beckoned with one lazy finger. "Come on out. Let me see you. I need to make sure you're telling the truth, don't I?"
"I..." Isabel suppressed another shiver at the thought of being exposed in front of someone else again, but she didn't have much of a choice. "Fine." Gingerly pushing open the stall door, she stepped out, one arm clasped across her bra, the other trying futilely to hide her lacy panties. "See?"
The brunette looked her up and down, none too subtly, making Isabel blush even more fiercely. It was all she could do to not make another run for it, but she forced herself to stand there while the girl inspected her with her eyes.
"So come on, you can see I'm telling the truth!" Isabel said desperately. "Can I have some clothes! I can pay you back later, I promise!"
