A lot of times, the fashion world give an already steady rating in class for individual, if you wear Gucci, Dior, Chanel, lipsy (basically designers popularly known), you tend to be seen as some one of class and its the highly placed that accepts you.
Converse is the case when you go on normal clothings( especially when names aren't famous), you are seen in a different light.
In all these its irrespective of how properly or improperly dressed you are, just wear a brand and you get your class.
