Why do girls in Japanese anime wear short skirts in winter?

Isn't it nice to solve it with short sleeves just like summer? ? So why do Japanese girls prefer to wear short skirts even if they are frozen into dogs? We need to analyze this reason from a deeper level: as we all know, Japan is a big cultural exporter, and the whole world is watching Japanese anime works, and Japanese female high school students, as the absolute protagonists in anime, have already become a cultural business card of Japan like anime.

In Japanese anime, Japanese female high school students wear miniskirts and stockings all year round, regardless of spring, summer, autumn and winter, which is of course for aesthetic reasons. After all, if every cartoonist changed his heroine into a school uniform, I'm afraid no one would watch Japanese anime long ago ...?

Therefore, in the cognition of foreigners, Japanese female high school students are such an image-youthful and beautiful, sailor suit, especially the absolute field between miniskirts and stockings, which is the essence of JK! Then the embarrassing thing came. Since people all over the world think that Japanese female high school students wear short skirts all year round, why can't Japan, as an economic power, play a joke on foreigners in terms of honesty?
