The vest originated from Han Dynasty. At the end of the Han Dynasty, Liu Xi said in "Shi Ming Shi Yi": "One of the crotches is the chest, and the other is the back." The crotch is the vest, which is further explained in Wang Xianqian's "Shi Ming Shu Zheng Supplement" It is clear: "The case is the half-back in the Tang and Song Dynasties, and today it is called a vest in common people. Be careful when carrying it, and it is also righteous." Xu Ke's "Qingyi Leichao·Clothes" also said: "Half-arm, Han Dynasty It was called an embroidered skirt at that time, which is now a waistcoat, also known as a vest." It can be seen that the vest was available in the Han Dynasty at least 2,000 years ago. There are many interesting anecdotes about vests in Chinese history. According to the records of "Southern History", during the Southern and Northern Dynasties, Xuzhou Governor Xue Andu "wore a crimson crotch shirt and galloped into the bandit formation" to kill the enemy. "Records" also describes vests: "During the great cause of the Sui Dynasty, many internal officials wore half coats, that is, long sleeves. Emperor Gaozu of the Tang Dynasty reduced the sleeves and called them half arms, which are now called backs. Between the Jianghuai River and Huaihe River, they may be called Chuozi. Scholars competed for uniforms. , it was made in the Sui Dynasty. Today it is commonly known as the vest, also known as the vest." It seems that Li Yuan, the emperor of the Tang Dynasty, was also an active advocate of the vest. Su Shi, a writer in the Northern Song Dynasty, also liked to wear vests. He was demoted to Hainan Island and returned to Changzhou after being demoted to Hainan Island for "slandering the imperial court." He wore a vest on his way back. This is recorded in Shao Bo's "Records of Shao's Hearings and Seeings": "Dongpo returned to Piling from overseas. He was ill due to summer heat. He wore a small crown and half of his arms. He was in a boat and watched by tens of millions of people on the bank of the canal. "
During the Wei, Jin, Southern and Northern Dynasties in China, the crotch was the prototype of a vest, which was an open-collared sleeveless tunic, imitating the double-dang armor of the Han Dynasty, taking its meaning of "be careful with your back". In the Song Dynasty, it was called a vest.
The suit originated in Europe in the 16th century. It is a collarless, sleeveless top with openings on both sides. It is about knee-length. It is mostly made of silk and satin and decorated with colorful embroidery. It is worn between the coat and shirt. After 1780, the body was shortened and worn with suits. Most of the suit vests now have single-row buttons, and a few have double-row buttons or a collar. Its characteristic is that the front part is made of the same fabric as the suit, the back part is made of the same lining as the suit, and some waists at the back are equipped with belt loops and clips to adjust the tightness.
