I tend to think that people like to wear knockoffs because they don't want to spend the $$$ for the designer look but want it anyway. Lets be honest...a LOT of people can't tell the difference, so maybe they aren't fooling people like us, but they are fooling the unenlightened masses which is probably good enough for them anyway. Sucks that people do it, but I highly doubt the knockoffs will stop being produced completely when the demand for them is so great.
Agreed. And what about that awkward moment when that one person calls out a bag as fake when in fact...genuine.
