This gorgeous Ben Zuckerman cocktail ensemble dates from the early 1960's. It features a dress with a daring low back and  a double breasted coat. The pattern is quite autumnal.

 

This is an interesting image, showing a suit jacket by Ben Zuckerman. The photo dates from 1965 and is quite artistic- it's hard to see the exact details of the jacket but it appears  to have several pockets and is single breasted.
