Penny, The dances and costumes WyoWoman has observed have been strongly influenced since World War II by the traditions of the northern plains, where WW lives. If you you want to represent 20th century Wyandots at a dance competition, WWs suggestions are good. If you want to represent 20th century Wyandots at church, then I'm not so sure feathered fans or dance shawls would be appropriate. If you want to represent 17th century Hurons, some of WW's suggestions might be appropriate (the modern shawls, feather fans, and fancy bustles didn't come out of nowhere) but you'll need to do a little more digging to establish provenance.

A list of tribes, with links to homepages, is at http://www.cherokee.org/navbar/nations.htm. I have not so far found a link to any site discussing historical AI dress and adornment, however.
