If some rapist found my outfit irresistible and raped me, presumably it'd be my fault according to her logic
No by her logic that would be rape (or "rape rape" possibly as coined by Whoopi Goldberg ) as you aren't dressing in a way to make yourself look attractive/catch men's attention.
I wonder where she would draw the line between say your dressed purely for utilitarian purposes, my very definitely dressed up as standard but not in a sexy way, my son's girlfriend in black shorts worn over thick black tights with ballet pumps ( of course it looks attractive, she's young, pretty and slim) and the women from the strip club on Lothian Road out for a fag break between acts with their high heels and shorty raincoats.
I expect I am off the hook as I'm still quite demure, my son's girlfriend, possibly, as she's wearing thick tights and flat shoes but the strippers are probably fair game.
