From Vogue, 1967- American Fashion Hits- Little Black Jacket Suits.
This suit, made near the end of Ben Zuckerman's career shows the increasing youthfulness of clothing in the late 60's. Gone are the hat and gloves, and the skirt length is much shorter than in the past. The suit is made up of a single breasted jacket and straight knee-length skirt. It also has a blouse with a bow at the collar. I imagine that this blouse is sleeveless and the cuffs seen are faux- this was a feature frequently used by Chanel to reduce the bulk of blouse sleeve under the jacket.
