Mark Buxton has developed around 200 fragrances. He knows which trends will prevail and why expensive is not always better.

Almost all new women's perfumes smell fruity, floral and slightly musky, he says. Buxton: Even noble brands like Chanel or Louis Vuitton make perfumes for the masses. "Fragrances have become an accessory. You want to smell like your girlfriend," says the perfumer, who works in a shop in Paris. "You can't digitize scents. You can't learn everything, but in the end it's creativity that decides," he adds.
