Why do Hanfu men's dresses have big tops and low skirts, while women's dresses are mostly one-piece?

Hanfu has a history of more than 4,000 years, and various styles have emerged during its development. When we talk about Hanfu, we usually mention the uniforms and dresses of Hanfu. In fact, there are four grades of Hanfu, which are uniforms, robes and sacrificial clothes. This is an ancient classification, and the concept of uniforms and dresses that we usually say is actually put forward in modern times.

Dress is actually relative to uniform. If it is really a dress, both the sacrificial dress and the royal dress can be regarded as dresses. However, looking at the history of Hanfu, one place is particularly interesting, that is, most of Hanfu men's dresses are divided up and down, that is, the "clothing system", while Hanfu women's dresses are the opposite, and Hanfu women's dresses are indeed one.

For example, a skirt, as a lady's uniform, is a system of top and bottom clothes:

Here is a double-breasted skirt, as well as a bust skirt, so I won't say much.

As the traditional dress of women in ancient Hanfu, colorful deep clothes.

Men's deep clothes, many people say that they can be worn as uniforms, but in fact, there is no concept of uniforms in ancient times, and men's deep clothes are definitely lower than the coat. Then the question comes: Why are most men's dresses in Hanfu separated up and down, while most women's dresses are integrated?

This can be said to be unexplained, because I haven't found the relevant literature for the time being. Just some intuitive guesses: men's clothes directly follow the weekly system, and it is more expensive to wear them on and off, while women's clothes are deep-dressed, which may be a metaphor for women's need for "single-mindedness".
