Vintage Boho Chocolate Brown Reversible Dress, Coat or Top

I bought this in a Vintage Store in Kansas City about 20 years ago. Great with tights and a turtleneck, but could work as a light coat, dress or long top. Only worn a few times and ready for a new adventurous dresser. Very unusual material, almost springy! Lots of stretch, but keeps its shape. See pxs. Has collar and 2 Side slits. Reversible with embroidered pattern on back and one sleeve on one side, other side is plain. No tags. Size M-XL. Back top of collar to hem about 50" Armpit to. armpit in front 20" Sleeve from shoulder seam to end 23" 7 double sided buttons
