This is a Ben Zuckerman jacket, once part of a suit, in a lovely textured wool. This jacket has the lovely, almost work of art, buttons that so many Zuckermans feature. The jacket has 3/4 length sleeves (all the better to display bracelets, or gloves that would have been worn by most women in the 1950's).

There is a scalloped design in satin running down the front of the jacket, and the collar and hem are also edged in satin, making a striking detail.
