First of all, we should know that skirts were first invented and were first worn by men. During the Spring, Autumn and Han Dynasties in China and the corresponding western countries in the same period, the form of clothing was similar to a skirt, but it was called a robe in China at that time, and women wore skirts a long time later than men.
Clothes were originally invented for warmth, not for beauty. As we all know, the average body temperature of men is higher than that of women, and men produce more calories. So there is a theory that men pay more attention to heat dissipation when wearing clothes, and women pay more attention to warmth when wearing clothes. As a kind of clothing style with good heat dissipation, skirt was loved by many men in ancient times. However, due to the imperfect indoor warm-keeping measures in ancient times, women's clothes were thicker, and the era of wearing skirts was later than that of men.
In China, wearing robes gradually evolved into a cultural symbol of the aristocratic system, which lasted until the late Qing Dynasty. At that time, dignitaries also liked to wear robes, and only ordinary people would wear underwear. However, the traditional robes in China were called skirts in the Han Dynasty. Although it is more masculine, it still has many similarities with skirt style.
Influenced by western culture in modern times, people began to choose to wear simpler and more flexible clothes instead of ancient robes, so skirts became exclusive to women and gradually became a solidified cultural concept, while men wearing skirts were regarded as sissies and perverts, and only ethnic minorities still retained the custom of men wearing long skirts.
But in fact, we should know that when popular women's clothes were first invented, many of them were for men. For example, stockings, short skirts and high heels are originally the dress styles of men in western upper class. Nowadays, it can be seen in many film and television works that western countries have such a dress custom, but it is not accepted by mainstream culture, so men prefer modern clothes and pants in clothing choice.
Apart from these factors, men are taller than women and have thicker waists. When wearing a skirt, men can take advantage of their figure to highlight the lines of the skirt instead of wearing a tight skirt to show off their figure, which most men have certain advantages over women. Now many popular elements have borrowed this style. Men's underwear becomes loose, and the legs are open, which is a bit like a skirt. Although many people subjectively say that it is unacceptable, it is quite good from the visual effect alone.
Modern culture is more tolerant and free, and you can wear any kind of personalized clothes without paying too much attention to the eyes of people around you. So now many men tend to be feminine in their clothes, which shows that modern aesthetics has changed in some aspects and is no longer bound by culture. For the time being, it is impossible to tell whether this change is good or bad, but as long as you like to wear what kind of clothes, that is your freedom. Be bold, sometimes it's good.
