Authentic. Do not have the original receipt but not concerned with authentication since I purchased directly from Prada in-store - could probably go back through my credit card statements during that time at request of buyer. Poshmark will authenticate! UPDATE: proof of purchase added to photos Good used condition! Few signs of wear on the main bag that are visible in photos. Inside of the bag is completely clean. I used this bag as a shoulder bag primarily with the chain, so the crossbody strap is in brand new condition. Selling as I just do not reach for it as much anymore.
