Mongolian costumes include robes, belts, boots and jewelry. However, due to different regions, there are also differences in styles. Take women's robes as an example. Influenced by Manchu, Mongolians in Horqin and Harqin wear wide and straight robes with split sides, and the neckline and cuffs are decorated with various colors. Mongolians in Xilingol grassland wear Mongolian robes with large narrow sleeves and no slits; Buryat women wear robes with waist skirts and shoulders; Ordos women's robes are divided into three pieces, the first is a close-fitting dress with sleeves reaching to the wrist, the second is a coat with sleeves reaching to the elbow, and the third is a collarless double-breasted vest with straight flashing buttons. The robes worn by Mongolians in Qinghai are similar to those of Tibetans. Except Qinghai, there is little difference in men's wear. Wear double robes in spring and autumn, single robe in summer, cotton robe or fur robe in winter. Mongolians usually like to wear Mongolian clothes.

Cloth clothes, usually wear brocade-rimmed clothes on holidays. Men's wear is mainly blue and brown, while women's wear likes to use red, pink, green and sky blue. Belt is an important part of Mongolian costume, made of satin or cotton cloth, three or four meters long. Men's belts are often decorated with knives, irons and snuff bottles. Mongolian boots are divided into leather boots and cloth boots. Mongolian boots are fine in workmanship and have exquisite patterns on their surfaces. Wearing jewelry and hats is a habit of Mongolians. Hats in different regions also have local characteristics. Mongolian hats in Inner Mongolia and Qinghai have a high top and a flat edge, lined with white felt, and decorated with leather or purple-green felt, which is thick in winter and thin in summer. The hat top is decorated with tassels, and the hat belt is made of silk, which can be worn by both men and women. In Hu Ba and Buryat Mongolia in Hulunbeier, men wear shawl hats and women wear pointed-brimmed hats. Precious raw materials such as agate, jade, coral, pearls and silver make Mongolian jewelry rich and luxurious. Men's colors are mostly blue and dark brown, and some people wrap their heads with silk. Women usually wrap their heads in red and blue headscarves and wear conical hats like men in winter. Mongolian men wear robes to tie their waists, women's sleeves are embroidered with lace patterns, and their coats are high-necked, which seems to be similar to ethnic groups. Women like to wear clothes of three different lengths. The first one is a close-fitting dress with sleeves reaching to the wrist, the second one is a coat with sleeves reaching to the elbow, and the third one is a collarless double-breasted vest with straight rows of flashing buttons, which is particularly eye-catching.
