From the article:
Rather than rely on obvious logos, expensive products use more discreet markers, such as distinctive design or detailing. High-end consumers prefer markers of status that are not decipherable by the mainstream. These signal group identity only to others with the connoisseurship to recognize their insider standing.
Another interesting point the article made was that many people / groups of people will wear very logo heavy clothing to show that they have “made it”, while “high class” people who have “made it” don’t want to show off their success in such obvious ways, such as the material, cut, or stitching of their clothing.
Example of clothing which communicates wealth with out logos:
I teach high school students, and many of my students often wear very (IMHO ugly as sin) logo intensive clothing. I’m looking forward to sharing this information with them.
