Large remnant of a Chinese  robe or  perhaps a collar section. Guessing on the period 1900-1940. 
From the estate of a well known doll maker who recreated authentic doll's clothing from period fabrics.

I think that you should be able to see from the photo with the tape measure, about how large this embroidered piece is.
Please ask me is you have any questions,.
There is a black and metallic edging, which I have posted a close up photo of.
