Start with her shirt

You watch as Megan works, fairly slowly, carrying books back and forth into the stock room and back out into display, wondering the best at to strike.

Finally making up your mind you wait as she passes into the back room and click your fingers. The sleeve of her shirt snags on a loose nail in the doorway, and suddenly tears completely from her body, causing her to stumble, dropping the books she was carrying.

"Damn it!" She cursed, pulling off the remnants of her shirt and leaving her in her t-shirt.
