Hi, do you think I'm being silly? I guess that's a good sign, but I just wanted to be extra careful. Someone on this thread said she bought a fake Prada bag from Saks Off 5th that was a returned item from Gilt (now owned by Saks, so Gilt customers can return items to Saks directly). I know that my Saks Off 5th store just opened yesterday (Grand Opening), so it's unlikely that they got any returns from Gilt customers. But you can never be too careful. I usually only buy designer bags directly from the boutiques, so this is completely new to me. I hope the authenticators here can help ease my mind.
Extra careful is good but it's frightening and sad to hear that you aren't even safe from fakes when you buy it from the store.
I've heard some stories about exchanges being superfakes and of course if the bag has no "flaws" they will sell it to someone else who thinks he/she gets the real deal.
