North Asia
Russians in Siberia are located at high latitudes and have a cold climate. In winter, they mainly wear leather boots. Of course, they have their own national costumes, such as shirts, saravan (sleeveless dress with shoulder straps) and vest (a sleeveless holiday dress without collar and buttons, usually with shoulder straps).
Mongolian costumes include jewelry, robes, belts and boots. Men, women and children like to wear robes all year round, double robes in spring and autumn, single robes in summer and cotton or fur robes in winter.
In the north of China, there's nothing to say, right? Summer shorts vest, winter cotton trousers.
South Asia
Because the temperature in this area is very high all year round, it is basically summer clothes, but every country is different.
Southeast Asian clothing, I think players will think of the words different styles and customs. Indeed, Malaysian fashion is bright, colorful and passionate, just like butterflies dancing; Thailand's fashion is fresh, elegant, comfortable and fashionable, full of romantic atmosphere of sunny beaches, like walking in coconut groves; Indonesia's fashion is elegant and gorgeous, just like a lady boarding an oil tanker and going out to sea, the sea breeze is comfortable and romantic; Vietnamese clothing pays attention to embroidery and splicing, and its workmanship is very fine. Gorgeous fashion reveals a strong national color, and the shadow of the national costume is faintly visible.
East Asia
I think Japan is a kimono, and North Korea and South Korea are Korean costumes. There are Tang-style cheongsam in China, and 56 ethnic groups in China have different costumes. Look for pictures on the internet by yourself.
west Asia
I think the main Arab countries in West Asia should be able to imagine that they are wearing robes, cloaks and headscarves with Arab customs, because the image of Arabs is because there are many deserts.
Having said that, you'd better look up the map online yourself. That's more intuitive. Every place has its own characteristics.
But it is always related to the geographical environment of other places.
