I don’t want to be rude, but I think I see the bag tag still attach on the bag. I hope she’s not the recurring returner. It’s a very nice bag and she actually seems to use it.
No worries, you're not being rude. I remember seeing the bag tag holder too, plus the protective plastic still covering the hardware and the dustbag peeking out from inside. That pic was posted on IG by an authorized Longchamp retailer and I assume that the person modeling the bag is a store employee. Many LC retailers post bag pics on IG in this manner.
