Smell is our most primal sense. It connects us to our animal selves more then our other senses do, a part of us we tend to deny. Tied to memory, desire, and seduction, scent is potently connected to our imagination:
"Perfume is potentially a carrier for the imagination. Perfume is thick; it is poison and pure desire; it is eros in person." -Serge Lutens
When has a scent seduced you?
