Anyone have information about a particular costume?

I remember an interview with Edith Head way back when, and she definitely took credit for the dress. I did notice that in the credits there is also a Raoul Pene du Bois something or other who was given credit for the wedding dress. But Edith for sure took credit for the bejewelled dress. I think she was on the Mike Douglas Show or something and talked about "rubies."

Raoul Pene Dubois designed the mink dress/skirt, although Edith Head preferred to take the credit!
In the Paramount Costume shop, the costume was like a mink RUG because of the weight. Studio wardrobe had a "fur vault" where pelts were kept for building fur coats, fur trim for costumes, etc... Usually, fur pelts were returned to the vault after being worn/filmed; being stripped from the costume the pelt had been used for, simply because of the pelt's value and fur pelts could be re-used. "Barbara 'MADAM KARINSKA" was borrowed from the "Kismet" Costume Crew to rework the "RUG" skirt because Ginger Rogers wouldn't, nor couldn't, perform in the costume. Karinska built a wire frame covered in a fine netting, spacing the mink pelts apart from each other, allowing each pelt to be independent, thus reducing the fur skirt's weight, and allowing Ginger to perform in the costume.

According to the Moviediva website, director Mitchell Leisen designed the costumes, including the spectacular mink gowns. Leisen worked as a costume designer, before he became a director.

The first mink dress, lined with glass beads, was too heavy for dancing. A second version of the mink dress was created, lined with sequins, which was lighter so that Ginger Rogers could dance in it.
