Amelie's shrinking clothes

(This story is public, you could add a chapter and anyone can contribute)

Amélie entered the lecture hall, pushing through the doors, speaking loudly to join her friends. The 18-year-old student was in her first year of college. She was often dressed in fairly long t-shirts, skinny jeans and perfecto jackets, like most girls her age. The class that day was taught by a rather authoritarian professor, who had already had the young student in her sights for several weeks. As she discovered the college, Amélie was surprised to see how casual the dress habits of the other students were. For example, even if it was very cold and rainy, one could always see a student in a crop top and low waist jeans, proudly showing her belly and her navel dripping under the rain, all under a light leather or denim jacket. The beautiful Amélie had never shown her belly in a top, and she wasn't interested. But that was about to change...

At the beginning of the class, Amélie was constantly being noticed by the teacher, and in the middle of the class. The teacher gave her a look that suddenly almost petrified her. The old woman then waved her hand, as if to resume her lesson, but in truth, she had simultaneously put an odious curse on the young student. In full laughter, Amélie stopped dead in her tracks and bent over, feeling her top being pulled up. In fact, it was going up for good. Amélie's white top was actually no longer long enough to cover her belly completely, and was coming up more and more. Terrified, the 18-year-old student watched her top now protrude past her belly button, continuing to get shorter and shorter. Amelie's white top kept getting shorter and shorter, but stopped when the young woman's entire belly was exposed, and her low-cut slim was not helping the situation: her lower abdomen and navel were also proudly exposed. The young girl wanted to hide her top, now a very short crop top, with her perfecto, but could not do it. The teacher had, without her knowing it, condemned her to wear crop tops and to show her belly and her navel for an indefinite period of time, during summer like winter.
