To lend a little help to the matter, I've read somewhere that your fragrance should only be noticed only when someone can discern the color of your eyes...a good gauge if you asked me. Hope this helps in that sense.
If you are worried somewhat about longevity, spray on your clothes or under your clothes to help the fragrance keep throughout the day.
Some people mistake fragrance with a lighthouse beacon for "ships" to find their way home.
Be careful in being mistaken for a lighthouse!
