Like you I've accumulated enough of most clothes to last for a considerable time - in fact probably to see me out. I've also been using the local charity shops as the equivalent of a clothes exchange since I retired, particularly for trousers, with a recent purchase of a light summer outer jacket as backup for the old (we're talking 1980s here) one I love but which is probably going to get beyond realistic mending, to be seen in public, in a year or so. I have bought two new t-shirts and one new sweat-shirt in that time, both because CATS. My only planned purchase-from-new will be underwear.
