I suspect you also didn’t dress provocatively to send mixed messages to your coworkers.
It amazes me how women think they can dress for a night club atmosphere and then complain that men are ogling them. HR needs to corral all the women young and old and give them rules for dressing: no cleavage or hint of the same, no skirts above the knees, no painted on pants. Naturally, men will feel sad but better that than some tart claiming someone made them feel “uncomfortable”.
