Clothes have aesthetics function. I love my Chloe dresses, how they made, how they look and feel aka they make me happy. I'm yet to find similar dresses in mass market or even just in other brands.

Most people who buy expensive clothing are actually doing it as a hobby, esp those that are being talked about in the article - people who are heavily invested in influences and celebrity culture, they find luxury to be fun and it allows them to hang out in circles of people with similar interests. So it does fulfill functions: aesthetic, social, entertainment etc.
