From 12 January 1964 New York Times. The centre suit is a lovely pinstriped Zuckerman suit. (The left suit is Bill Blass for Maurice Rentner and on the right is an Adele Simpson suit).

'Braid binds the shaped jacket of a striped wool suit that unbuttons on a white shantung shirt with a pleated bib and perky tie. $375.' 

Zuckerman was always at the forefront of American fashion, as is illustrated in this photo.
