Why do Indians and Pakistanis like to wear those pure white clothes? Is there any origin?

The most common clothing for Indian men is "Totti", just like the clothes that Gandhi wears in the movies. "Totti" is actually a piece of white cloth three or four meters long, wrapped around the waist, down to the knees, and some down to the feet. With the development of society, men's clothes have also improved. In addition to "Totti", the upper body also added a fat shirt named "Gu Erda". It's cold, add a shawl. On some particularly important occasions, we often see some elderly people wearing "Gu Erda", "Totti" and slippers. Foreigners who don't know the inside story often think that these people are insignificant. In fact, this kind of dress is the most important symbol. But in the city, men's wear has tended to westernize, and suits are almost the most common men's wear. Even if you don't wear formal clothes, it's western-style shirts and trousers. Indian men, especially important government officials, often wear a coat that looks like a "Chinese tunic suit" on formal occasions, with a tight neckline, a pocket on the chest and a pen inserted, which also looks very energetic.
