There are two ways to present A Guide to Spotting Fake Louis Vuitton Bags. In the first scenario, an author might offer tips to fashion insiders who like nothing more than to point out the pitiful girl who slung a Canal Street knockoff over her shoulder and thought she'd get away with it. In the second scenario, it's the buyers of such fake goods who get the service-y treatment, with a how-to on how to spot fake Vuitton goods before buying them. This is one of those guides. But, uh, word to the wise? If you find yourself in a place — and that includes eBay — where you even have to question whether the bag you're buying might be fake, well, then it is.
