Chanel No. 5 isn’t just a perfume; it’s a cultural phenomenon. Known as the world’s most iconic fragrance, Chanel No. 5 was revolutionary when it was launched, with its innovative blend of aldehydes—a synthetic compound that gives a fresh, airy feel—and florals. This was unlike any fragrance at the time, which made it an instant classic. With notes of ylang-ylang, jasmine, and sandalwood, No. 5 has a complex, powdery bouquet that manages to be both soft and bold.
