This is a fantastic Ben Zuckerman ensemble, consisting of a dress and jacket. The material is a golden weave and is really striking.

The dress is quite plain and is a sheath shape. It has a great belt- large and very decorative. The jacket is double breasted and has stunning buttons which add to the overall dressy feel of this outfit.

You can see in the bottom pictures that this outfit retailed at Saks Fifth Avenue. The tag has a name on it- which is hard to read, but this would be the purchaser of this great outfit. And most interestingly of all there is the purchase date -9/27/65, so this outfit can be very specifically dated.
