Who are you getting teased by? The people in the locker room who should be used to girls in their underwear doesn't make any sense. idk but I would ignore the whole thing and not trust my sister again.

Hahahahahaha! Well just have a sense of humor about it and time will pass and you will be over it. Stuff happens. We all have our own embarrassing moments. And this is a funny story you can tell people someday.
