Sillage
Sillage is the scent trail a fragrance leaves in the air around and behind the wearer. The name comes from the French word for "wake".
Sillage is related to, but different from, projection (how far the scent radiates from the skin) and longevity (how long it lasts). A fragrance can last all day close to the skin and still have little sillage, which is why evaluators judge the three separately.
