In 1921, Gabrielle Chanel requested the help of Ernest Beaux to create a "woman's fragrance that smells like a woman", rare and powerful. The nose presented her with a visionary composition that made unprecedented use of aldehydes. Mademoiselle chose the fifth sample of the fragrance, and decided to simply name it "N°5". For this new fragrance, she chose a radical design for the bottle, adorned with a white label and topped with a faceted cabochon. The unique scent of N°5, along with its simple name and bottle, revolutionised the history of perfumery and has gone on to achieve cult status.
