Say it’s for respect, say it’s because of religion, say it’s just a rule and don’t ask questions, say it’s arbitrary and sexist. Just don’t say we need to wear high necklines and low hems so that we are not sexually harassed. Don’t do it. Don’t victim blame, don’t lie. In harassment-heavy countries like Cuba and Egypt, I have seen anecdotally that the amount of clothing is irrelevant. Cuban guys say piropos to all women, regardless of clothing and almost regardless of age. White women get slightly more commentary, but no amount of clothing will make me less of a gringa.
In Egypt, it has been found that women believe they get harassed less when they cover up more (more being even more than we do in the West, since it includes the abaya, the hijab and the niqab.) However, these same women actually self-report higher levels of harassment when they are more covered. It’s just an instance of intense cognitive dissonance, egged on by years of messaging from men, women, harassers and victims alike claiming, as if in some desperate plea for relief, that if only we could wear the right amount and combination of clothing, they would just leave us the hell alone. But they don’t. Women in full abaya and hijab get raped in public. Women in jeans and modest shirts are assaulted all the time.
To say that I can stop (or even stem) harassment by changing my clothes is an indictment of women and men alike. It says men cannot control themselves and thus need to be prevented from seeing that which entices them so. It says women who get harassed must not have dressed properly, it must be their fault somehow.
It still boggles me that otherwise-progressive people fall into this trap.
