I had one very similar to it back in the late 70's or '80's. I would have been in my teens at the time. It was white with lovely embroidery on the back but mine was not silk (more like a rayon/cotton mix). It wore it over pj's. It was just a short, lightweight robe for use in warmer seasons. Someone gave it to me as a gift but I cannot remember who it was. I have a feeling it was obtained from an overseas trip. It was a lovely garment though and I think mine just wore out in the end until I threw it away.
