Eh. "Accepted" is probably a relative term here. As in, she was probably not "accepted" the way a man would be in casual attire. She just had slightly fewer hurdles to jump.
In any case, the point here is that men's reactions to women in dresses often cause distress and make women feel uncomfortable in technical settings. That's frankly ridiculous, since (as far as I understand) many women like to wear dresses and don't feel that they're formal. Maybe it's due to a misunderstanding? Men labor under the misapprehension that dresses are formal attire when they're not, and that causes the disconnect, etc. etc. Doesn't mean we should just accept it -- let's correct the misunderstanding. :)
