"The Oklahoma Feather Dancer or “fancy dancer” is one of the most popular style of dance and outfit seen at modern Pow Wows. The fancy dance outfit, as such, has no single tribal identity.
The “Fancy Dance” originated as Fancy War Dance by the Hethuska society in Oklahoma. The individual who invented the dance was Gus McDonald. He was also the first World Champion Fancy War Dancer. The McDonald family, specifically Juel Farmer McDonald, the Ponca Tribal matriarch still presents the trophy to the fancy war dance champion each year because of this family honor." - from Feather Fancy Dancing on Powwows.com
