From February 1964 Harper's Bazaar- Ben Zuckerman on the cover.
This is a really unusual suit from Ben Zuckerman. It is a sleeveless jacket, double breasted with a curved seam on the front of the jacket. Large mother-of-pearl buttons decorate the jacket as well. Worn underneath the jacket is a blouse in a khaki colour, probably also by Zuckerman, as well as a matching skirt.
