ANTIQUE HENDERSON AMES Native American regalia clothing suit Indian -War Company For Sale

What and amazing piece. This was manufactured by Henderson Ames Co., Military and society goods. It\'s a total mystery as I can find anything like it. I see Henderson became the Henderson Ames Co in 1893. I\'m unsure if this was made for a special purpose for ceremonial use or theatre? The item is very stained as shown, some of the leather frill is very dried out and brittle. As shown in photos.
