NWT JPeterman black beaded back zipper shell

NWT J Peterman black beaded shell. So well made w/back zipper, silk lining, hook & eye closures on sides to allow for more or less opening. This has never been worn, but I believe it must have gotten wet since there are stains from metal (on top zipper) & beading, both on the lining. Doesn’t affect the outside look, nor will it be seen except by owner. Stunning. Made in India.
