I was about to think it was real (even with the little minor inaccuracies), until I saw his white Detective:
The CD engraving on the handle buckles is very cheap-looking (I compared them with the handles on my denim Detective, and the ones in the pic were definitely fake). Also, the logo on the interior leather flap is more inaccurate than the black one. As well, the interior logo lining is Dior jacquard, and it shouldn't be unless it is the denim Detective bag (all solid-color Detective bags had tan and white logo flowers lining).
These fakes are similar to those 99%-accurate LV fakes...just ONE or two details give them away.
