Wear-time comparisons
How long do light perfumes last on skin
Light can mean an airy scent, a quieter presence or a lighter-positioned format. None supplies one fixed skin-wear duration, so clarify which meaning you want before comparing products.
A HUME Fragrance buying guide

Define light precisely
A delicate-smelling composition can remain noticeable, while a quietly worn fragrance may still have a warm character. Style and presence are different observations.
Check what remains later
A perfume can become less noticeable around you while retaining a close-range trace. Decide whether that suits the occasion instead of treating all quietness as disappearance.
Use exact candidates
A broad adjective is not a product specification. Keep the version, application and setting recorded so another trial can be compared meaningfully.
Try this before you buy
Write whether light means scent texture, surrounding presence or format in your shortlist.
