I knew designer labels had a psychological effect on people who see them, but I am surprised by the size of the effects discovered by researchers at Tilburg University in the Netherlands. They found that people in designer labelled clothes were rated as significantly higher status and wealthier than those in the same clothes sans labels. They found that 52% of people would take a survey from a person in a Tommy Hilfiger garment, compared with 13% for the same garment without the logo. They also found people more willing to give a job to someone bearing a designer logo, with a recommended salary 9% higher.
The strategies suggested by this data are pretty obvious: even if it seems a bit tasteless, it may be wise to emblazon yourself with labels, especially when dealing with strangers.
