If you wear perfume, you walk the fine line all the time ‑- between overdoing it and underdoing it. The goal is to wear enough fragrance to feel good and make the right impression. But how do you prevent yourself from smelling like you just shopped the fragrance floor at Bloomingdale's? Experts tell us it's a combination of using common sense, knowing your body chemistry and adhering to the rules in fragrance-free zones. Here's what they say.

The cardinal rule is don't use too much. It may seem obvious, but sometimes we absent-mindedly spritz our pulse points, our garments, our hair, our necks, without thinking. That's overkill. "French perfumer Annick Goutal always said a great fragrance is the secret between one's self and one's self," says Tom Crutchfield, business manager for Etro Fragrances at Bergdorf Goodman and a 20-year perfume-world veteran. Think of it this way, he says: You want your fragrance to please you most of all, or those who get closest to you. "Once it goes beyond your two-foot to three-foot personal space, perhaps you put on a bit more than you want to."
