On May 15th, 1968, French jeweler Arnaud Clerc organized the first ever International Diamond Fair in Paris. Paco Rabanne dressed Françoise Hardy for the occasion in one of his iconic metal dresses.
However it was not constructed of aluminum, steel or Rhodoid like his other "unwearable" creations. This dress was composed of 1000 joined gold plaques, weighing nearly 38 kilos, and the collar was incrusted with 300 carats of diamonds.
Hardy arrived at Place de l'Opera in an armored truck, accompanied by armed guards. Indeed, at the time it was dubbed "the world's most expensive dress" by the media.
The event was immortalized by Jean-Marie Périer, then the singer's compagnon.
