Noticeability
Are light perfumes noticeable to other people
A light-smelling perfume can still be noticeable to others. Airy character, lower projection and a lighter-positioned version are different descriptions, so identify which meaning matters before interpreting feedback.
A HUME Fragrance buying guide

Read the actual description
Light does not specify a uniform formula or radius. Check the exact fragrance and format rather than assuming a delicate character means nobody will notice it.
Choose appropriate presence
Follow the rules of shared spaces and describe the level of noticeability you want. Being quietly present can be a useful result rather than a failure.
Compare perspectives
Your awareness can differ from a willing observer's report. Record both with setting and stage of wear, without treating one experience as universal.
Try this before you buy
Write whether you want light texture, quiet presence or both before asking for feedback on a candidate.
