Over my years in the workforce, business attire for men has changed little: colored dress shirts and ties for self-expression. Women have always had a greater choice when it came to office attire: dress, skirt and blouse, pants, some other combination.
With this choice comes a dilemma for some: How to look professional, while exercising some form of self-expression.
While 99.99% of women dress appropriately for the office, there are always outliers, whose wardrobe choices are in poor taste to put it diplomatically.
Rather than single those people our (the brave and correct thing to do), they decide "punish all for the crimes of one". Why is this done? I suspect for several reasons:
1.) Those empowered to coach do not do it well;
2.) Those empowered to coach have a history of imperfect conduct themselves;
3.) The organization fears a lawsuit, and, addresses the issue in a manner that uses the path of lease resistance.
