Please post any authentication requests you may have here, taking care to follow the prescribed format as well as ensuring all the required pictures are available (see the first post of this thread), and we can look into them.But how can you tell? I'm looking at these online and I don't know what clues to seek.
In response to your earlier query, those of us who offer assistance with authentication do so from a generally good knowledge of Dior products. Most of the time we can make reasonably confident assessments because of that knowledge and also many of us have had a good amount of experience in handling Dior product in real life, so we know what to look out for. We do our best to help but if the answers we provide aren't "convincing" enough for you then there is nothing further that we can do for you.
