Vintage Old Hollywood Glamour Robe

Gorgeous robe, not sure which decade exactly as there are no tags. Could be 70s or 80s does 40s. Color is sort of an off-black with black detailing. No size listed, so I included measurements. Fabric isn't listed, but it feels like nylon, or a blend. Excellent vintage condition - no holes, stains, or rips that I can find.
