The Sioux were an ancient American tribe who inhabited North America. They wore clothing made from buffalo skin, deerskin, or elk skin. During colder weather, they wore buffalo hide cloaks. They also wore soft leather shoes called moccasins. Sioux people hunted buffalo and used its hide for food and blankets. The buffalo was also used as a building material, and the skin was tanned. They also wore beadwork and adorned their outfits with geometric designs and ornaments.
