Many of the details of this bag match up with the real thing (especially the logo on the leather charm that hands with the D I O R metal charms). However, the inside of the bag appears to be a different story. The leather flap that says Dior is sewn very croakedly (actually, it is sewn croakedly onto the lining AND the sewing is croaked around the flap...it almost looks cheaply done, and at over $1000/bag, this usually doesn't appear); the Christian Dior PARIS words are very croaked as well; and the interior red cannage lining looks very suspicious because the CD logo on the lining doesn't look very right (even though you can really only see one of them), and the lining seems to have a corduroy appearance with vertically-running lines. Here is what the real one looks like:
The lines aren't in this one, although this is the exact same lining. Notice especially the cannage motif...they're just not the same although they should be.
Maybe this is an older version and I've just never seen it before, but I would take this to the boutique to verify its authenticity if I were you, unless other PFers who has seen this can correct me.
