This outfit dates from 1964- it's a formal ensemble, featuring a dress or a long skirt and top, and a double breasted jacket in heavy wool.
The model was photographed by David Bailey, one of the world's top fashion photographers.

This Ben Zuckerman suit dates from 1955. It is made of a dark wool- perhaps grey?- with a straight skirt and a long jacket.

Model Sondra Peterson wears a textured white matelassé theatre suit with matching mink trimmed jacket by Ben Zuckerman.

This is an undated Ben Zuckerman coat- it's a striking look.

The coat has an asymmetrical closure, and almost resembles a dress. The self belt adds flair. All in all, this is a lovely outfit.

This ensemble dates from 1961 and is worn by model Sondra Peterson, a top model of that era.
The dress is a long column made of Matelassé,  a weaving or stitching technique yielding a pattern that appears quilted or padded. Matelassé may be achieved by hand, on a jacquard loom, or a quilting machine. It is meant to mimic the style of hand-stitched quilts made in Marseilles, France. It is a heavy, thick textile that appears to be padded, but actually has no padding within the fabric.
