I'm working on a short story of girls in a class who ultimately decide for themselves nudity is better than dealing with constant pranks from their male classmates. The premise is a naked girl telling a fully clothed, transfer student why all the girls in this particular class are naked all the time, but it's not mandatory.
I'm having trouble deciding on one part though.
"Shoes - in the beginning someone, we're not quite sure, was stealing our shoes from the locker Amy chance they got. We told the teachers, but they just told us to solve it ourselves. It got so frequent that some girls just decided to start going barefoot. I guess we could wear socks, but they'd just get dirty.
Skirts - the boys thought it was the funniest thing in the world to mess with our skirts. They'd lift them, close them in doors, position fans so they'd blow up... we spent all day worrying about who would see our panties and when, but one day, Ayumi had enough and just took her skirt off after some boys wouldn't stop lifting it. And you know what? The boys got bored and didn't bother her. Eventually we just all stopped wearing skirts.
Shirts -
Bra - After we all agreed to stop wearing shirts, we noticed it wasn't fair since Miki and Yumi didn't wear bras, and they were the most reluctant to agree. To be fair, we all went without.
Panties - Can you believe it, we were all walking around in nothing but our panties but they still found would mess with them. It started simple, just pulling them down, which was annoying, but then they'd start taking them expecting us to chase them. They'd do things like cut them up or hang them high out of reach and yeah... it's just easier to be naked, you know.
That was all years ago though so you're probably okay... "
It's supposed to be a gradual process. I think of a reason the shirts would be lost.
