Can we make unified dress code for all human beings worldwide some day?

Why should we? First of all a unified dress code for everyone would mean we are one culture, which we're not. It would have to make traditional dress of different cultures illegal, which would itself cause problems. Second of all people have the right to be individuals, something dress codes attempt to do away with. The idea that dress codes stop problems is foolish as problems continue to exist despite a dress code. And if one is in place long enough then people will revolt against it. When a dress code is put in place in a school how many kids keep following the dress code once they get home? They know perfectly well that once they get home they can wear whatever they want to get away from the dress code. Thirdly, whose going to decide on what folks should wear? It'll be up to politicians to make that decision and international politics have shown that nations rarely agree enough for anyone to pick a unified dress code for all humans.
