The original source was the “Junon” dress, designed by Christian Dior for his 1949/1950 Fall/Winter collection. Pale-blue silk net embroidered with iridescent blue, green, and rust sequins. The dress resides in the Metropolitan Museum of Art’s permanent collection a gift of Mrs. Byron C. Foy, 1953.
When I saw press photos online for the Broadway musical “Wicked” I realized it was very similar to the Dior dress I've drooled over for many years. “Wicked” opened on Broadway in 2003. The costumes were designed by Susan Hilferty and the dress was worn by the character Glinda originated by Kristen Chenoweth (who rules!). Ms. Hilferty won the Tony for Best Costume design that year. The costume has been on display at the NY Public Library before, and it was described by the website as "Dior -inspired". Perhaps she isn't shy; imitation is the best form of flattery.

The sad part is that neither newer version really stands up to the original by Dior. The moral here is; Leave well enough alone.
