Zum Zum Prom Dress, Black Formal Gown, Vintage Cocktail Party Mini

This Zum Zum vintage mini dress from the '70s and '80s features a fitted silhouette with ruching at the bodice and thin shoulder straps, crafted from stretchy black polyester that's fully lined and back-zip closure. The piece captures classic cocktail-party energy, though the low-cut neckline and mini length mean it works best as a statement piece rather than everyday wear. Given the vintage sizing, we recommend checking measurements carefully before purchasing.
