girls in coed gym class shirts vs skins

This is no serious poll as it assumes that girls might completely strip to the waist (not even wearing bras) in pe which is absolutely nonsense especially in coed pe. Every pe teacher who would arrange that would immediately lose his job and the girls would of course refuse. In our highschool we had sometimes coed pe with shirt and skin games (basketball) but only boys were shirtless. Girls joining the skin team of course kept their shirts and had pinnies for distinction.
