Examine the bottle within its purchase context
Authenticity cannot be read solely from glass thickness or cap shape. Begin with the product’s origin, commercial documents and the reference ordered. Visual details help identify questions to ask; they cannot replace coherent traceability or a clear response from the seller about the bottle supplied with your purchase.
Avoid confusing official variations with irregularities
Changes to a pump, label or box may accompany an official presentation update. Look for information matching the version and market concerned before reaching a conclusion. If uncertainty remains, send photographs of the bottle and packaging to the house instead of using the fragrance as an improvised authenticity test.
