Vintage Steven Stolman black knit maxi dress, labeled size 6

In EUC and in time for Halloween. So many possibilities. Turtleneck Morticia? Padded shoulders, 12” seams on the set-in sleeves, and a turtleneck with ruching on the back that closes with 2 snaps. A very fine knit. No fabric tags or washing instructions. From a nonsmoking, no pet household.
