Nowadays any celeb worth their Z-list status brings out a perfume every Christmas, but the first person to release a globally successful scent was Coco Chanel, with Chanel No. 5 in 1919. It is the most popular perfume of all time, with a bottle being sold roughly every 30 seconds. Chanel’s flagship boutique on Old Bond Street – the biggest Chanel shop in the world – displays their other famous fragrances (Coco Chanel, Allure, Mademoiselle Coco, and No. 19 among others) in spectacular surroundings decorated with strings of real pearls, crystals and specially commissioned artworks.
