I find this list of precautions to avoid rape very instructive.
OP - it does go beyond your suggestion of chaste clothing. It's pretty exhaustive.
Don?t go out and get drunk, it could lead to you getting raped. Also, don?t have sex with someone because it could get you raped by someone they know. Don?t be young, that could definitely get you raped. While we?re at it, especially don?t be a child, that could really get you raped. Don?t be older either, that can get you raped. Don?t be living in a nursing home; women get raped there. In fact, what are you even doing in an establishment like that, are you asking for it? Don?t be single; single girls are sluts. Sluts get themselves raped. Don?t be married either or you could get raped by your husband. Don?t go jogging, that is just irresponsible. Don?t go to carparks, that can get you raped. And really don?t go jogging in a carpark, that is like so going to get you raped. Don?t go to public toilets, that can lead to rape. Don?t be dying; dying women get raped. Don?t ever be unconscious for any reason whatsoever, you?ll get yourself raped. Don?t be injured either. Raped. Avoid being physically disabled. Raped. And particularly avoid being intellectually disabled. You couldn?t get yourself more raped. Don?t go out alone, that is dangerous and you could get raped. But don?t accept lifts either; that is just asking for trouble. Don?t ever be naked, it could get you raped. Don?t wear clothing in which I could imagine you naked, that could get you raped. Don?t wear short skirts, they attract rape. Don?t wear baggy clothing or pyjamas or hospital gowns or a hijab either, women get raped in all those too. Don?t have a father, brother, uncle or grandfather. You could get raped by one of them. And oh my god, don?t even think about having a step-father. So raped. Don?t be ugly or you could deserve rape. Don?t be beautiful, you will be too tempting. Don?t flirt with men, this can get you raped. Don?t be rude to men either ? playing with fire. Don?t take public transport. Raped. Don?t drive your own car, what if someone hid in the back seat, you could get raped. Don?t sell sex or anything close to it. Raped, raped, raped. Don?t be mistaken for someone who might sell sex. Obviously, you would get raped. Don?t be a soldier, a waitress, a teacher, a police officer, or a hairdresser. All these women can get raped, sometimes by their professional colleagues. Don?t dance, it could lead to you getting raped. Don?t relax, what if it made you look like you wanted it. Don?t be stupid, that will surely get you raped. Don?t be naive, you?ll deserve what comes to you. Don?t be adventurous, that is being stupid and stupid women get raped. Don?t be silent, who can be expected to know you didn?t want to be raped. Don?t be intimidated, that can signal weakness and will get you raped. Don?t be trusting, don?t be in awe, don?t be flattered by anyone ? that could so get you raped. Especially don?t be female, that could really get you raped, although being male could get you raped too, so don?t do that either. And don?t be interesex or trans, people will think rape is for your own good.
