Rare One-of-a-kind Vintage Maxi Dress with Embroidered Element - Pit to pit 17"

In great condition. The brand tag is missing but I found a listing on Etsy for a dress that has the SAME material/embriodery. The brand on that was Mariella Ami and it is Made in Roma, Italy. From the late 60s/early 70's. Either way it is a gorgeous relic from my favorite eras!
