Why do I not smell my fragrance after I have worn it for awhile?

The nose tires easily and any scent always present eventually disappears from awareness. After a period of smelling a fragrance you become used to it and may not be able to smell the scent. The scent is still there and is very strong for others. Do not trust your own sense of smell to decide how much is enough. It will always smell less intense to you than it does to others.
