Clothes have always had an extra feature of displaying status. Expensive clothes are purchased for both their quality and status appeal, and thus, are worth it as long as you can afford it. If status and quality are worth the price, then obviously it's not a bad thing to purchase the expensive clothes.
Expensive clothes are not worth buying at all! The only exception to this rule is if they were made in the United States and the people buying them are supporting their community. Expensive clothes are a waste of money. The regular clothes that people can buy from regular shopping stores are decent and trendy enough for most people, unless one has money to throw away or show off.
