Diorissimo
Diorissimo is a floral perfume by French master perfumier Edmond Roudnitska. Originally introduced in 1956, Diorissimo is an attempt to simulate lily of the valley, since no essential oils can be obtained from the actual flowers. Diorissimo also has notes of ylang-ylang, amaryllis, boronia and jasmine. Diorissimo has been reformulated to comply with the regulations of International Fragrance Association (IFRA).
