Mongolian costumes are mainly distributed in the Inner Mongolia Autonomous Region and the Mongolian-inhabited areas of Heilongjiang, Jilin, Liaoning, Xinjiang, Gansu, Qinghai, Yunnan and other provinces and autonomous regions. Mongolian costumes are one of the most representative costumes of the northern nomadic peoples in my country. They have developed unprecedentedly in the Yuan Dynasty and have become luxurious, magnificent, elegant and sophisticated. With the continuous changes in society, the Mongolian tribes have independent development space, and the types and categories of Mongolian costumes have continued to increase, forming different characteristics of the costumes of each tribe and continuing to this day. The costumes of each Mongolian tribe are distinguished by men, women, old and young, married and unmarried, four seasons, ceremonial costumes, and daily costumes. They mainly include robes (single robes, padded robes, cotton robes, hanging leather robes, white stubble leather robes, smoked leather robes), waistcoats (Aoji, Aojimuge), boots (felt boots, fragrant cowhide boots, Mahai), headdresses and accessories (fire, saddlebags, fragrant purses) and other parts. The Mongolians have lived in the northern grasslands for a long time. The harsh and cold plateau climate, coupled with a nomadic lifestyle, means that they spend a long time on horseback. Their clothing must have a strong cold-proof effect and be easy to ride. Long robes, waistcoats, leather hats, and leather boots naturally become their first choice of clothing, thus having a strong grassland style. The robes are mostly made of leather, wool, cotton, and silk fabrics, depending on the season. The robes are bulky, the sleeves are long, and the hems are not slit. The collars, cuffs, and hems of Mongolian robes are often decorated with brocade lace, and the color of the robes varies depending on the age of men and women. They mostly like red, white, blue, yellow, and green. The color matching is either strong in contrast, bright and warm, or elegant, coordinated, and subtle. The belts are very long, and men often hang knives, fire, snuff boxes and other ornaments on their belts. Women's headdresses are mostly made of jewelry and gold, silver, and jade, which are dazzling and magnificent. From the perspective of clothing styles, Mongolian clothing is wide-sleeved, elegant and dignified, which can not only reflect the curvaceous beauty of Mongolian women, but also reflect the bravery, generosity, and rough and open character of herdsmen. Among them, religious clothing and Mongolian wrestling clothing also have their own characteristics and uses. Mongolian clothing integrates cutting and sewing, precious metal processing, and jewelry making. It is an inseparable part of Mongolian culture. It embodies the wisdom of the Mongolian people and shows rich cultural connotations. It has research value in history, ethnology, aesthetics, etc.
