Hey Girlies, Quick question/thought: have any of you ever gotten a bag authenticated at a LV boutique and find out later that the bag was indeed a fake? Does this happen? Is a SA allowed to say it's authentic withouth being a 100% sure? If so, this makes me SUPER nervous about buying a used LV ever! Not only from a mypoupette seller, but from friends and other sources. What do you guys think/know??
