The dress is Christian Dior Hatue Coture collection, Palladium dress, Spring/Summer 1992, and was on display from May 14 to September 25, 2011 at ‘Dior, le bal des artistes’ exhibit in the Villa Les Rhumbs. -fukufashion
This was the dress that inspired Princess Serenity’s dress in Sailor Moon. In the Materials Art Book (as seen above) you can see some of the original sketches for the dress look quite similar to this dress.
Note: I’m currently looking for fukufashion’s original post of the dress.
