A chunk of her tank top had caught and a thread trailed behind her

(chapter originally by SpiralFelix at writing.com)

Isabel opened her locker and pulled her bag out. She had a spare t-shirt and sweatshirt along with some loose, baggy shorts. She had planned to change into these after her workout was done but she had no hesitation about putting some on now.

She pulled the shorts up over her hips and tied the drawstring at the top to make sure they had no chance of falling down.

Isabel examined the useless spandex scrap that she now held. Man, these shorts are ruined... But at least I've got a backup. Now I can get back to my workout. That was when she noticed the pink thread leading up to the back of her tank top. What used to hang down several inches below her breasts now stopped about an inch above her pink sports bra.

After another fifteen minutes of attracting stares from the men and women behind her, Isabel hopped off the treadmill, now wearing just a sports bra, shorts and thong.

Oblivious to the loss of her shirt, Isabel decided that next she would do
