On the other hand, I selectively use fakes to save money. For example, if I wear a pair of Manolo's, I can get by with wearing them with, say, linen pants from Old Navy, and everyone will tell me how great I look. Or I'll buy, say, a Marc Jacobs jacket at Neiman Marcus and put it with an inexpensive pair of pants and T-shirt from The Gap, and my friends think the entire outfit is Marc Jacobs. Another example is jewelry - as long as I have on anything expensive (clothes, shoes, bag, jewelry), I can get by with cubic zirc stud earrings instead of real ones. People assume it's all real.
A fake LV or Prada bag, on the other hand, doesn't last long. I've tried that, and I don't do it any more.
