Sadly there is no prevention. This is something that will happen. This, for the largest part depends
on the hasser...not the harassed
We can only take a bit of precaution but is there 100% prevention? I doubt it. Kono purush jodi kono mohila ke harass korte chae, shey korbei ebong at least try korbe even if it means the woman is wearing a borkha. Ar jodi kono purush kono mohila ke harass korte na chae, then whatever she is wearing, however she is walking around will be no issue to him
