Vintage ABAYA Middle East embroidered maxi dress

Vintage long maxi in Middle Eastern style like an abaya. Full coverage, with long bell sleeves and an A-line cut. May be specifically Muslim, or from Morocco, or something else entirely. Regardless, it is beautiful, with saturated amber and red and detailed embroidery largely in teal blue, white, and black. The tag script calls to mind Swahili and Arabic, but I can’t translate. No fabric content tag. GUC. Marked size S, which seems correct. Shown on a size 4 mannequin, 5’9”.
