good question, not stupid at all! i know people who have been wearing eau sauvage by guerlain for the last 30 years and will never even try another. i also know women who got hooked on chanel allure and will not change bottle after bottle. there are other examples too. i haven't found mine although there was a time i kept coming back to armani classic for men. it has a certain 'je ne sais quoi' i think it is pheromones from a the white tail deer jus kidding!
