In addition to the integrated strap thing above, this style with those metal hinges is also a common fake. This is listed by taskyou123 and has a fake label (oh, and all these pastel horizontal stripe bags are FAKE!)
Speaking of those fakes above, notice that this fake Prada (from navygirl1962) is the identical style as those 2 above, but with a fake Prada label. Counterfeiters stick whatever label they want! She expects $149.99 for this fake!
navygirl1962 says this is "hard to find" and is starting bidding at $79.99... Did she not notice the fake label is crooked??
