The trail of scent a wearer leaves in the air while moving, distinct from how far a fragrance projects or how long it lasts.
Sillage describes a fragrance’s trail through the air as its wearer moves. Perfume house Marc-Antoine Barrois distinguishes it from projection, the area of scent around a person standing still, and longevity, the time a fragrance remains perceptible on skin. These describe different aspects of wearing a scent, so one observation cannot establish all three. A fragrance that is noticeable close to the wearer at a particular moment has demonstrated presence there, while sillage concerns the trail associated with movement. Keeping the terms separate allows a more precise description of the fragrance experience.

Fragrance advisors meet this word in training and at the counter more than in a vacancy. It helps a client compare fragrances, and it should be kept apart from longevity, which describes how long a scent lasts on the skin. Search local jobs for “fragrance”.
