Absolutely amazing authentic 1960s or early 70s hostess maxi dress

This is a stunning turquoise, blue and gold embellished maxi hostess dress from the late 60s or early 70s. It is in great vintage condition. I can’t find any flaws. There are no tags. I think the outside is a heavy silk and the inside is lines in rayon the sleeves and neck are embellished with gold ribbon and gold sequins. There is a long working zipper in the back. It is a size small. Please message me if you need specific measurements.
