I have mixed feelings about it as well and I believe that different people have different reasons for sporting the fake LV's.
There is a girl on my bus every morning who carries an extremely fake black MC speedy. She does not dress well and clearly doesn't appear to invest a lot of time/money into style or fashion. I figure that she probably doesn't know any better and just bought it because she thought it was cute and saw other people carrying similar fakes. I don't think she was trying to fool anyone or come across as someone shes not. I do feel kinda sick to my stomach everytime I look at her bag, and probably have weird looks on my face everytime I eye it up.
There truly isn't a good substitute for an authentic black speedy. They are breathtaking IRL!!!
