Unique silvery woven patchwork unlined cocoon coat

Wonderful unlined cocoon shaped coat with deep shawl collar, dropped shoulders. Bound with widen black satin around collar, hem, front opening. Sleeves have a serged hem so they can be rolled up for any length arm. Unique silvery black woven patchwork textile-seems to be a slightly metallic rayon with a woven crinkle. Very cool item -can be worn as an evening coat! Not easy to measure-about 44” pit to pit including placket. Let me know if you need more info! I don’t think it’s ever been worn.
