"Veblen goods are types of luxury goods for which the quantity demanded increases as the price increases, an apparent contradiction of the law of demand, resulting in an upward-sloping demand curve. Some goods become more desirable because of their high prices."
The suits are expensive, so they must be good. It's also a status signal to others that you can afford such goods. (Edit minor typo).
