This is a Ben Zuckerman coat, dating from the mid 1960's, in bright lime green. It is trimmed in ivory at the closing, cuffs, collar and pockets and has large gold buttons that give a nautical feel. It also has a half belt at the back.
This coat, with its more youthful cut and colour shows that Ben Zuckerman was moving with the times, as by the mid 1960's fashion was featuring younger designs.
