Everything You Want to Know About All 5 Chanel No.5 Fragrances

Shop it: Chanel No.5 Parfum ($125-$325)

History: Perfumer Ernest Beaux created the now-iconic fragrance in 1921. Gabrielle instructed him to make a scent that was "a woman's fragrance that smells like women . . . I want to give women an artificial fragrance. I say artificial because it will be fabricated. I want a fragrance that is composed."

Scent: The original No.5 is the most potent and long-lasting version of it. Parfums typically have 15 to 40 percent fragrance oil, so diehards can enjoy smelling it from dawn to dusk.
