ISO Vintage Kaftan Cocoon Dress

I know it’s a longshot, but I’m hoping to find this piece. It’s vintage from the 1970s and the brand is Miss Bierner Originals. It’s a caftan like dress with angel/cocoon sleeves, metallic striped fabric. Please let me know if you see it or happen to have this treasure yourself! I’d love to buy. DO NOT BUY THIS LISTING - IM LOOKING TO FIND THIS ITEM MYSELF, IM NOT SELLING.
