This is why people wear undershirts... I mean, I don't because I wear a jacket even if it's 90 degrees out, but an undershirt helps hide your bra. Actually, I wonder why summer uniforms aren't a color that people can't see through. Like, if it really gets that hot EVERY SUMMER, some consideration for the students who are self conscious about that bras or nipples being seen through their shirt could benefit from a non-white color shirt
