I wonder how common it is for the opposite to be true. I think visible logos on clothig are phenomenally tacky and have a strong immediate negative reaction to the people wearing them when I see them. This isn't really a reaction to certain brands, but to the idea of advertising them.
On the other hand, I might assume that these people are wealthier.

After reading this, I'm seriously considering finding someplace online that sells those little Lacoste crocodiles and sewing them onto all my shirts. The power of logos appears to be ridiculous for the trivial outlay.
