Did you know that Headdresses are not historically traditional attire for Yakama men?

 "What was Yakama clothing like? Did they wear feather headdresses and face paint?
Yakama men wore breech clouts with leggings and short buckskin shirts with patterns of holes punched into them. Women wore buckskin dresses decorated with beads and quillwork. Like most Native Americans, Yakama people wore moccasins on their feet. Here is a website with Native American mocassins. In colder weather, Yakamas also wore fur robes and hats. Here is a museum exhibit of Yakama and other Indian beaded clothing, and some photos and links about Indian fashion in general.

Originally, Yakama men didn't wear headdresses, (Emphasis added). As they became more influenced by styles of the Plains and the Eastern Plateau, many Yakama men began to wear feather warbonnet headdresses like the Sioux. Yakama women usually wore fez-shaped basket caps, but brides wore a long beaded wedding headdress. Yakama women sometimes painted their faces, using different designs for festive occasions and religious festivals. Yakama men didn't usually paint or tattoo themselves. Most Yakamas wore their hair either long and loose or in two long braids, cutting their hair only when they were in mourning. Some Yakama men wrapped their braids in fur in the Plains Indian fashion.

Today, some Yakama people still have moccasins or a basket hat, but they wear modern clothes like jeans instead of breechcloths... and they only wear feathers in their hair on special occasions like a dance."
