Through four years in high school, I had never really been into wearing "revealing" clothes. I was never "big" which didn't help either. However, over the last couple years, my breasts got considerably bigger, and this year, I started going to school in sexier clothing. Little did I know the first day I did so it backfired.
It was the third day of school, and, as a dare from a friend, I showed up at school in my new minskirt, about four or five inches above my knee; without panties. I was also wearing a white polo, with a red bra underneath.
Coming down the stairs after third period, I quickly glanced back at someone I thought called my name. However, the minute I turned around, a guy coming up the stairs hit me, and I fell down the stairs, I landed head first, with my legs up, revealing my privates to everyone who wished to look.
And because I had just fallen, I couldn't cover myself up until after everyone around had seen it.
I haven't gone back to wearing normal clothes, but always wear panties. People still talk about the incident, and I don't think it will ever go away. Whenever I wear a skirt, they always ask, "Are you wearing panties today?"
