"Men were to exhibit good manners and ambition."
Ah, yes! I do remember those days. The women, on the other hand, were to remain at their desks behind their IBM Selectrics outside those furnished offices.
Men used to wear jackets, ties, and hats when attending sporting events, too.
Sorry, but wearing a suit these days in our profession usually means you're either there for an interview or will be going to a mid-day funeral.
Good writing, however, doesn't go out of fashion. My colleagues, men and women, write just as well now as they did decades ago. Of course, there are... and always were... the exceptions.
