You find your favorite perfume and suddenly that fragrance becomes your scent.  it’s something that identifies you and you want it to last all day.

If you apply a body lotion or cream with the same scent as your fragrance followed by applying the fragrance itself will make the scent last longer without its being too strong or overwhelming

Try it, do the layering on one arm and spray the fragrance alone on the other and compare. You will definitely notice a difference!
