Why did the Soviet women's army wear skirts to fight in World War II?

Wearing pants in the Soviet Union was only a male privilege, women were not entitled to wear them, even these female soldiers who fought on the battlefield for their country. As we all know, what is not allowed to do, often the rebel mentality will make people want to do these things the more. So there have been women who wore pants and were not only sanctioned by the authorities, but also ridiculed by everyone, who felt that it was something else, so it seems that women not being able to wear pants has become the default truth. In fact, not only the Soviet Union has such a custom, in many European countries women are not allowed to wear pants.
