An ad, in the February 1956 Harper's Bazaar.

This is the same coat that was worn by Princess Grace when she arrived in Monaco to marry Prince Rainier. Also part of this ensemble is a dress, which is not seen.

Judith Balaban Quine, bridesmaid to Princess Grace, talks of this coat in her book 'The Bridesmaids'. To quote 'Grace and I had gone shopping in New York. Though we had very different taste and completely different looks, each of us was partial to the American designer Ben Zuckerman. We had made individual visits to his showroom and then gone there together. We bought not only woolen suits and coats but also silk suits, satin coats and his new daytime spring coats of lightweight silk woven like gabardine. Two weeks earlier, when Rita Gam had married, recalling that we had purchased some duplications from Zuckerman, we had called each other before the wedding to make sure we weren't wearing the same outfit to the wedding. Yet it had slipped my mind to check about the arrival in Monaco. I imagined Grace would wear an outfit that had been custom-designed for the occasion, not just something 'off the rack' from Zuckerman. Now here I was, not four feet away from her, wearing a different hat, but a coat that was identical and distinctive- princess-shaped, small-collared and tied just under the bust with a thin bow of the coat fabric.'
