What is a one-sentence summary of the following article?
Only members of the Native American tribes in the Great Plains region traditionally wear the warbonnet. Films and tourist shows in the United States often dressed up other Native Americans or even white actors in fake warbonnet costumes, and many people now incorrectly associate it with native Americans across the New World.  Examples of tribes that use the warbonnet include the Sioux, Crow, Blackfeet, Cheyenne, and Plains Cree. In the original tribes that invented the warbonnet, only male chiefs and warriors wear them. They were, and still are, presented as a great honor and reserved mostly for formal ceremonies. Much like a military uniform, a crown, or other status symbols, people in these cultures do not make and wear warbonnets for fun, or without earning the right to wear them. If you are not wearing a warbonnet as part of a ceremony organized by a Great Plains tribe, many members of those tribes may not appreciate you wearing the warbonnet. Even Native Americans of other tribes may ask you to remove it, as they or their relatives may have been forced to wear it for tourism purposes, or stereotyped and bullied with references to the warbonnet. Even if you do not agree with another person's interpretation, removing the warbonnet in his presence demonstrates respect and politeness.  The eagle feather is sometimes considered a mark of special honor, and using one of these in a warbonnet may cause additional offense. Many tribes have additional sacred feathers, such as owl feathers, although these are not usually used in warbonnets.
