Vntg? Metallic green ankle dress

Fairly certain this is vintage as it was purchased at a dressmaker estatesale, but it's in such good condition I'm afraid to say so! Metallic emerald green mock turtle neck dress with side slit. Perfect for wedding, a classy prom, anything! I love this thing! No size or tags as she made them... I'd say it's like a 4-6? It fits me feel free to ask questions!
