Clarifying authenticity
Authenticity questions for perfume websites
Ask a perfume website whose fragrance it supplies, who sells it and how any brand-authorization claim can be independently checked. A broad original guarantee is weaker than clear product identity and traceable information.
A HUME Fragrance buying guide

Ask for exact identity
Confirm maker, version, concentration label and selected volume rather than relying on a reference name.
Check the claimed channel
Use the maker's own retailer or contact information where available. A seller badge alone is not confirmation.
Keep limits explicit
Codes, seals and photographs can inform questions but do not conclusively authenticate every delivered product.
Try this before you buy
Ask which independently checkable fact supports the website's claim about the exact maker.
