Beautiful, vintage black dress

Beautiful,sleeveless, v-neck black dress with a large front pocket with white embroidered design. Gathers at the waist with a wide circle skirt. Side zipper. It had a belt, but you don't need it, though perhaps a thin, red belt would add a nice bit of color. In very good condition, no flaws. Size and material are unknown but feels like a medium weight cotton. It measures pit to pit 20, waist 15, length 46 1/2.
