Well maybe they wouldn't bother you so much if you wore a bra.
Do you mean that you could see their breasts?
How else will I know if they are wearing a bra?
Women do get attacked no matter what they wear so assuming that they are asking for it by not wearing a bra is problematic. It is blaming them and it will make them feel guilty, just like people saying it is your fault for getting rob for not locking the door.
