Longevity, projection, and sillage explained
Separate how long a perfume lasts, how noticeable it is around you, and the trail it leaves in a useful wearing record.

“Strong” can mean several different things in a perfume review. Separating longevity, projection, and sillage makes the description more useful and helps you choose a fragrance for the way you want to wear it.
Longevity: how long you notice it
Longevity describes persistence over time. In a personal notebook, record when you applied the fragrance and when you last noticed it. Say whether you noticed it naturally or only by bringing the scented area close to your nose.
Avoid filling in an exact finish time if you did not check. “Still noticeable at dinner; not checked afterward” is more honest than turning that observation into a precise duration. One wear describes one set of circumstances.
Projection: how far it seems to reach
Projection describes how noticeable a fragrance is around its wearer. You can record whether it felt close, surrounding, or prominent in your immediate space. These are personal descriptions, not laboratory distance measurements.
A fragrance can last for a long time while remaining quiet. Another may feel very noticeable at first and become close quickly. Keeping those dimensions separate helps explain why two people can call the same perfume both “subtle” and “lasting.”
Sillage: the impression left in passing
Sillage describes the scent trail associated with movement. It is difficult to judge from your own wrist. If someone freely offers an observation, note the setting and how long after application it occurred. Do not turn a lack of comments into evidence that nobody can smell your fragrance.
In shared spaces, other people's comfort matters more than proving a trail. Follow fragrance-free policies and avoid asking people to participate in a scent test when they have not chosen to do so.
Record the conditions
Useful context includes the exact fragrance version, approximate application, skin or another manufacturer-approved surface, indoor or outdoor setting, and the time of your observation. You can add the weather if it helps you remember the day, without treating it as an explanation for every difference.
If you cannot smell the fragrance, pause before adding more. Your own perception is not a reliable measure of what everyone around you notices. Taking a break from evaluating it may be more useful than repeated close sniffing or immediate reapplication.
Decide what works for you
Longer, louder, and more noticeable are not automatic measures of quality. You might want a quiet scent for a short outing or enjoy a persistent scent that stays close. Write the outcome in relation to the occasion: “comfortable for a shared office” or “more present than I wanted on the train.”
Use a fragrance journal to record those observations. For workplace choices, continue with fragrance in shared spaces.
