For me, sustainability is a process of consciousness, i.e. to think things until the end. It means, for example, producing products in a way they are durable and repairable. This also includes the use of classic basics that can be combined well and thus changed over and over again, whether in fashion, interior design, etc. Upcycling is also a variation of this, here you often have something very stylish, individual … One should start before recycling!
