This is a Ben Zuckerman ensemble in rich black silk. The ensemble is made up of a sleeveless dress with an a-line skirt and a short jacket with 3/4 length sleeves and a ring collar.
The material of this outfit is a heavy silk with a slight sheen to it.
I would date this suit to the early 1960's as it has a slight Jacqueline Kennedy feel to it.
