We've all heard how buying counterfeit goods negatively impacts the fashion industry, but when the real deal--like high-end designer handbags or sunglasses--costs as much as a mortgage payment, it's easy to see why buying a fake is so tempting.  What you may not have realized, however, is how toting around a knockoff can affect your moral compass. Psychologist, author, and James B. Duke Professor of Psychology and Behavioral Economics at Duke University, Dan Ariely, has done studies on this topic and discovered that one act of cheating (like wearing imposter designer sunglasses) easily leads to another act of cheating. Ultimately, says Ariely, "Wearing imitation designer clothing or accessories can fool others--but no matter how convincing the knockoff, you never, of course, fool yourself."

So instead of sliding down that slippery slope filled with fakes, Adam Glassman, O's Creative Director, recommends staying on the straight and narrow in style. To raise awareness about the counterfeit issue and celebrate original design, the CFDA (Council of Fashion Designers of America) recently partnered with eBay and asked 50 designers--from Coach to Tory Burch--to create one-of-a-kind tote bags emblazoned with the slogan, "You Can't Fake Fashion." While these bags (which went up on eBay today) sold out faster than you can say "sale," you can still get your hands on the plain tote with this ultra-fashionable motto for $35 and customize it yourself. Plus, all the proceeds benefit the CFDA Foundation. Check out the gallery of designer totes online and get inspired to keep it real.

Have you ever purchased a fake? How did it make you feel? Did you find that you acted differently while wearing it?
