Won't the clothes in ancient Thailand fall off?

Thai costume is the national costume of Thailand. Men's wear is a stand-up collar coat with trousers or a square skirt, and women's wear is a skirt made of a rectangular piece of silk tightly wrapped around the waist. The tightness is adjusted with a rope and will not fall off.

Thai national costumes are very popular in Thailand and are widely worn. Thailand's national clothes are divided into men's clothes and women's clothes. Men's wear is a stand-up collar coat with trousers or a square skirt. Men's jackets are called sueaphraratchathen, with long sleeves for formal wear and short sleeves for everyday wear. Women's wear is the skirt under the coat, and the square skirt is called "phasin". It is a skirt made of a rectangular piece of silk tightly wrapped around the waist, and the tightness is adjusted with a rope. New clothes can be wrapped from left to right or from right to left. A coat can go with a jacket and a shirt. Formal dress also requires a belt that goes diagonally across the upper body.
