Clarifying authenticity
Authenticity questions for designer tester sellers
For a claimed designer tester, ask what tester means, what condition is supplied and how the brand identity claim can be checked. Presentation differences are not authenticity certificates.
A HUME Fragrance buying guide

Clarify the product
Confirm demonstration bottle versus retail item or small trial format, with exact maker and version.
Ask about condition
Record stated use history, volume and included cap or box. Check the selected offer rather than a generic photo.
Verify claims independently
Consult the brand's official retailer information where available. Do not rely solely on printed tester text or a code lookup.
Try this before you buy
Separate the tester-condition description from the evidence for the claimed designer origin.
