Good idea: supporting school spirit. Okay idea: borrowing a skirt from a female friend for school crossdressing day. Bad idea: forgetting to ask your friend and grabbing a dress out of your sister's laundry without looking. Terrible idea: pulling the dress out in the cafeteria to show your friends. It will be a cosplay nurse dress that has basically no cover below. The principal will see it along with the entire school. you will never live it down. World's worst idea: wearing the dress.
