This is an interesting ensemble. I bought it 2nd hand. It's handmade, not by someone who is particularly skilled nor using the highest quality hides.
I think they're deerskin but they may be elk. It's been in storage for the last decade, and needs a new home. It is not new; it has been worn in ceremony. It has a small triangular scarf in matching hide that is used as a neck piece (not pictured).
Measures 22 inches across the chest, so fits a ladies size XL. The item "2 PIECE SET! Natural buckskin / deerskin / hide top and skirt pow wow regalia" is in sale since Thursday, September 13, 2018.
