I also wonder why anyone would care what women wear.
Women usually dress for occasions, not to drive around, drive through fast food restaurants, grocery or
mall shopping, or walk in a park. Either they have a job that calls for a dress code a bit fancier than a uniform, dining at nice restaurants, go to clubs, symphonies/plays, weddings/fancy dances, or cruise ship events. I work at a concert venue and believe me, the women dress to the nines there. (However, they do not dress up for the hockey games). You will see women dressed up at events that call for dressing up. So don't expect to see women doing mundane things in a dress, heels, and (ugh.. hose!!) unless they are running an errand on the way home from work.
Just an observation, but I rarely see men on the street in suits anymore. I wouldn't complain about it, why should they dress up to go to a store? However, they do dress up at the same venues that I mentioned that women dress up for. I am assuming that men dress for the occasion also.
