Dior Diorissimo is a romantic fragrance that is fresh, clear and dewy like a Spring morning. A gorgeous lily-of-the-valley fragrance, Christian Dior believed that lily-of-the valley was the symbol of hope, happiness and joy. French consider lily of the valley as the legendary flower. According to the legend a brave and fearless fighter, Saint Leonard, wanted to spend his days among the flowers and trees and live a life dedicated to God. He asked permission to go live in the woods. A dragon called Temptetaion lived in those woods. Leonard bravely fought the dragon until it was defeated. Poisonous weeds began to grow where the dragon spilled his blood, but beds of lilies of the valley started to grow wherever the ground was moistened with Saint Leonard's. The French believe that lily-of-the valley is a holy flower and so did Christian Dior which inspired the creation of this wonderful fragrance.

Diorissimo was created by Edmond Roudnitska who wanted to create a perfume that would be revolutionary and break the trend of sweet perfumes that were dominating the market. The goal was to simplify the formula and create a perfume that was simple and luminous similar to that of the muguet that enveloped his senses when he was resting in his garden. Dior and Roudnitska met in 1955 and made their dream come true in 1956. According to Christian Dior, Diorissimo was the perfume of his spirit, "the scented expression of his soul".

As far as I can tell, the EDT and extrait that you can purchase now are the original Roudnitska creation (reformulated, of course). In March of 2011, Dior released a new version of Diorissimo as an eau de parfum and that was created by Francois Demachy, Dior's in-house perfumer.

This is the original eau de toilette (Roudnitska) version of the fragrance.
