I believe in the idea we shouldn't encourage material values as happiness. To start that, I envision a world where we should support thrifting and making our clothes last longer. Even when we donate our old clothes most of them still go to waste. One way we could do this is have clothing swaps and have people in neighborhoods bring there old clothes and trade them with others for clothes they like. I remember when I outgrew my baby clothes, they were given to my younger sibling or even to neighbors who had younger kids who needed them. This could also better build community relationships with others. The research shows that your happiness isn't impacted by material possessions but our relationships with other people. The happiness you may feel when buying new items like clothing is ultimately short-term and because of that people will feel that they need to buy more to get that happiness again and it becomes this cycle of buying things again and again multiple times.
