Its already late in History and there are still a lot of things that "normal" men wouldn't wear. And it has nothing to do with personal taste (leaving aside the fact that education allows our choices very little freedom).
What would everybody think if your company's big boss (male) showed up in the morning dressed in a pink suit, his hair styled in a French twist? Would he be less of a male? Would he be less of a boss? But why?
Do we still need all that attrezzo? (I mean dark colours and neckties and all that staff)
