"Just as music is art for the ear and painting is art for the eye, perfume is art for the nose."

It's amazing how certain scents can evoke the mind. How we translate scent is dependent on someone's perspective. It is purely by emotions, whether it reminds you of an old song, memories of the past or possibly even something exotic. Each time you take a whiff of something, it takes you to a place... whether it be home, somewhere comforting or possibly even somewhere frightening. Generally, people like to correlate scents to something rather positive.
Why do I where perfume? I have a signature scent, and I wear it for me. The scent brings out my character, it's the best way to describe myself without using emotive language.
But of course, you can describe a scent using emotive language, which is always aesthetic and stimulating.
