This is a really special Ben Zuckerman coat and dress set in a bright blue, green and yellow floral pattern. The dress is a sheath style and is influenced by Jacqueline Kennedy. The coat is single breasted with 3/4 length sleeves. It fastens with the most amazing buttons.
What makes this outfit so unique is that it is from the Sax's Fifth Avenue Custom Shop. Here ladies would go to have one of a kind outfits made by top designers. This Zuckerman is dated 28 April 1964. The customer would have gone to the Custom Shop and would have worked directly with Ben Zuckerman, picking the material and having the outfit made to fit her exact measurements. As you would expect this was a very costly exercise so very few women would have been able to afford this. It is very likely that this outfit is one of a kind.
