She enters it normally, but now she realized something...

How is she supposed to change into her gym clothes? All other girls wear underwear, so it's not that embarrassing, but her, with only a shirt and a really short skirt...

For now, she just approached her locker and took out her white, gym shirt and dark-blue bloomers. All other girls were busy with talking to each other and getting dressed, so none spotted her humiliating state of dress. She used that fact and went to the showers, where she hid herself. She took of her skirt, undid buttons on her school shirt, took off her pantyhose and shoes, leaving herself in a state of complete nakedness. It was really embarrassing, even though she was in fact under the showers. She tried not to think about it too much and quickly put up her bloomers, which were pretty tight, especially without any panties, and her simple, white shirt. It could be a disaster. Without any bra, how is she supposed to run, or do anything, when her boobs can bounce so much under this? She will have to take it easy for today. Slow and steady.

She returned her bag into the locker, while having a weird feeling of being observed from every side from other girls in the changing room, and went into the gym lessons.
