Everyone has a personal "scent circle": approximately an arm's length from the body. No one should be aware of your fragrance unless he or she steps inside your "circle."
Fragrance should be one of the most subtle, personal messages you send to those with whom you come in contact.
Perfume and Fragrance
For a long-lasting effect, fragrance should be layered all over the body, starting with toilet water or eau de parfum, next in strength to perfume, to build the fragrance foundation. Because fragrance rises, spray or smooth fragrance onto skin from the feet to the shoulders. If fragrance is applied only behind the ears, it will eventually rise and disappear.
The wearer's diet can affect the way a fragrance smells and lasts on the skin. If the wearer is on a high fat, spicy diet, for example, fragrances will be more intense. A dramatic change in diet can alter skin chemistry, causing fragrances to smell differently.
Skin type will also affect the way a fragrance smells on a person. Fragrance wearers with oilier skin should remember that fragrances interact with the oils in their skin to create a more intense scent. Dry skin does not retain fragrance as long as oily skin, requiring the wearer to re-apply the fragrance more often.
