Well, for a brand to stay in business, they have to sell. So it's really unrealistic to expect access to nice, designer bags and for no one else to have said bags. Just cannot happen.
Let's just be honest here. When people say "this brand is too common" what they are suggesting is an annoyance that *anyone* can now access and afford the same bag as them. The horrors! No one will think you are important and special anymore for carrying
Coach or MK! Now, if these people *really* wanted something truly unique, they'd order from a small designer or have something custom made. But then we have the same horrors, because no one will know that it's special, unique, and most important of all, elite. What these people are really searching for is a brand recognizable enough to be admired, but not accessible to the average person. Sorry, I know I'm being harsh, but I really don't have too much sympathy for people staring down their noses at the common folk.
