I certainly don't buy things to throw away in 6 months.
I own tracksuit pants that are over 10 years old and still in good condition. I don't buy clothes every season. I buy clothes when I need them. Just recently I had to throw away my favourite jeans that I bought in USA in 2006. So I went out and bought a new pair. I own 2 pairs of jeans. Most of my clothes are years old.
My trainers are over 2 years old, although I suspect I need new ones as I have a heel injury which is probably caused by my old shoes.
My favourite converse died as well. They were also over 10 years old and had to be replaced. I was gutted that they didn't have the same style anymore.
I have less than 10 pairs of shoes. I've got 1 converse, 1 trainers, 1 pair short boots, 1 pair white heels, 1 pair black heels, 1 pair flats, 1 pair thongs. That's it. The pairs of heels are both well over 5 years old. I don't wear them much so they're in very good condition.
