Social needs, birds of a feather flock together. People in that circle think that luxury goods represent taste, strength, pursuit of Excellence and attention to detail, and the brand has been given a higher spiritual symbol! Not just an object, but a part of life. To give a real example, a boss usually wears a Dior shirt. Once his wife bought him a g2000 shirt, so did his husband, but there was a problem when the boss wore it to a party with friends. A friend asked privately, why is business bad recently? Dressed so quietly. All right, that's it. Later, the boss stopped wearing small brands. People in that circle are very concerned. Whether it's true or not, it's because that brand of things can bring some different feelings. That's why you say hypocrisy or show off.
