Actually dressing too well probably adds to people's cognitive dissonance. If her intention is to exploit this to her advantage, then that's one way to go about it... probably better then the OP's. The OP didn't say anything about how she was dressed for these interviews. I'd put down good money that she was dressed better than the average SE. Just because some schmucks are tactless enough to blurt their confusion doesn't necessarily make them "sexist".
