Why do upper-class people wear suits?

People in high society don't have to wear suits. At Diaoyutai State Guest Officer, the formal attire is: Chinese tunic suit, suit, Tang suit, dress (including all kinds of robes and cheongsam), uniform (formal attire of all state organs) and national costume.

Have you ever seen Mao Zedong in a suit? What about Deng Xiaoping?

In addition, Hu Shi and Chiang Kai-shek never wear suits.

It can be seen that the upper class in China has no tradition of wearing a suit.

What about now? It is precisely because suits are recognized by most countries and nations in the world that wearing suits is to show respect for each other.

But wearing national costumes is also very formal, and it is also widespread in the upper class. For example, Sohu CEO Zhang Chaoyang and movie star Jackie Chan. In public, most of them wear Tang suits or robes.

Well, it's the same in other parts of the world. For example, Libyan President Muammar Gaddafi, billionaire bin Laden, and North Korean President Kim Jong Il. Don't wear a suit in public.

For western countries and western immigrant countries, this problem does not exist, because suits are people's traditional national costumes, not a fashion problem, and everyone is wearing them.
