The best thing to do is probably to buy high quality clothes and keep them for a long time. Don't buy t-shirts (especially printed t-shirts) that wear out quickly and get disposed of. Buy shirts and take care of them. Don't wash them often. Wash then minimally when they become dirty. They'll last you many years this way.
