Why do traditional costumes decline and modern costumes become the mainstream?

Very simply, traditional clothing cello and modern clothing have become the mainstream, because traditional clothing is not suitable for production and work, and now serving is relatively convenient and inspection is more reasonable. In the past, there was basically no embodiment of figure, so it did not conform to the current aesthetics, and it was really inconvenient to wear and work, so traditional clothing could not decline. After all, if you wear traditional clothes in daily life, you can't do anything. In addition, it is a waste of time and trouble to wear, and it is worse in many functions. For example, if you want to be cold in winter, basically. Traditional Buddha statues have the same effect of keeping out the cold, but the gap with down jackets is too big. In addition, for example, in some functions such as sweatpants, it is not as normal as it is now. In fact, some clothes like the past are falling. The main reason for the decline now is that suits are not so popular.
