Oh, (Miss) Canada
From what I can find, I don't think Chelsae is Native. But honestly, that wouldn't have mattered. That's a straight-up costume shop headdress right there.
The sad thing is, she had an opportunity to do something cool. Look at her dress (once she moved the cigar store Indian arms):

Also, I suspect the skirt is supposed to represent a teepee.
"Homage" = mockery
So it's an "homage" to and "inspired" by Haida art? In other words, it's some non-Haida version of Haida art. And not a good one.
Maybe one of the elementary-school children she loves created it for her. A kid saw a chief, wolf face, and teepee in an Indian coloring book and put them all in a costume.
The polite term for this is cultural appropriation. Another term might be "mockery" or "ripoff."
As you may recall, last year a Miss Universe Canada finalist also appeared in a headdress. A few years ago, Miss USA appeared in a headdress:
It's hard to say which of these costumes is worse. Miss USA's sexy showgirl outfit turned her into an Indian princess, fantasy figure, and potential abuse or rape victim. But Miss Universe Canada's outfit bastardizes a real culture's artwork by 1) copying it badly and 2) mixing it with the stupidest Plains stereotypes. I wonder if Durocher did a war whoop or dance to go along with her dress.
