I got this bag as a gift, and determined it was fake, for the following reasons - hope this helps...
1. The size was ~2cm smaller width than the authentic ones I bought in a store - I checked 3 Pliage against it - all 3 store bought were the same size, this bag wasn’t. So i knew immediately.
2. Handles were slightly squishy, and too rounded. They definitely had a foam core - real pliage are just leather, and firm.
3. the fabric felt “off”... too rigid and almost crunchy, compared to my store bought ones.
The diagonal hash pattern can be a bit of a red herring... You can see my original, 20-yr. old Pliage (bought at Nordstrom) has a deep hash embossed on the leather... but the just-purchased (from a Longchamp store) Club, the hash is not as deep - more surface. And there’s a huge texture difference in the flap underside.
So I suggest start with with edge to edge width, then handles, and if either of those are off, you’re in the same boat as me. If they’re good, move on to checking the embossing and hardware - that the jockey faces the right direction and looks the right level of detail (mine faced correct direction, but too little definition).
Good luck!
stay safe!
