I could smell someone's perfume from ten feet away today and I have severe allergies, so that's not good. Perfume should be something that people can smell when they're in close contact with you. After all, it's supposed to mimic pheromones and you don't want every person who passes within ten feet of you to smell it. It's best done minimally (and that'll save you money). For the sake of everyone around you, especially those with allergies, just keep it light! Don't overdo it!
