I have been wearing fragrances since the mid 1960's and I have always done the following:
- Spray each wrist and both sides of the neck before leaving home.
- Spray a little on both sides of shirt before leaving for lunch.
- When leaving work, reapply like the morning and before lunch but very lightly.
Heavy sprays for light fragrances, medium sprays for regular strength fragrances and light sprays for heavy fragrances.
For heavy fragrances, I like to buy a minitures and use them before lunch and before leaving the office rather than spraying.
For light fragrances, I also spray the back of the neck or behind the ears.
I try to use the bath products in the morning when available.
I learned here at Basenotes, that rubbing the fragrance clouds the scent, and I no longer do that.
