The description says "elaborate full dress" but I see material that looks like it's plaid. I'm very ignorant about traditional Native American garb, but I suspect that the Chippawa didn't traditionally wear plaid (that seems more like an Irish or Scottish material to me). Can anyone elaborate on the clothing? Would this be something designed for one of the old 'Wild West' shows?
The plaid of which you speak could easily have been a gift, the result of a trade, etc. Most of the tribes east of the Mississippi, and a considerable number of tribes west of the Mississippi, made and wore cloth garments, and much of the fabric was acquired through trade with Europeans. In fact, there is a whole category of fabric called "trade cloth" for fairly obvious reasons. Don't fall victim to the stereotype that Indians wore nothing but skins.
Also I've never seen a picture of a Native American with a mustache. Is that something that was more likely grown for a show (or maybe a result of the photographer's lighting)?
Again, don't fall victim to a stereotype. I know that men of the tribes of the Southeast (Choctaw,Chickasaw, Cherokee, Creek, Seminole) often sported facial hair, though not nearly to the degree that Europeans did. I cannot speak for the Chippewa and Ojibwe (collectively aka Anishinabe) on this, but I think Ottowa Creek Bill might.
