I already get rid of anything that is uncomfortable or does not fit or but I keep things that are less than pristine for work involving dirt, sweat, mud, sawdust, polyfilla dust, paint and so on. These are only worn around the house and garden.
I hate buying clothes - no, change that to "I hate shopping for clothes". I am happy to buy them, but I hate searching endless racks for the size and style I want, stripping down to underwear in a tiny cubicle to try on possiblities and then dressing again because they look awful and moving on somewhere else to scan the racks, the assistants who eventually notice me searching and condescend to produce what they think I am looking for. It never is.
The truth is, I only know I am looking for it when I find it. My best buys have been things that I loved the moment I saw them hanging there, that fitted perfectly and made me look ten times better. There is no way of predicting which they are. I just have to slog around until I find them.
So I don't have a lot of clothes. The same things go round and round, added to from time to time, and subtracted from when something gets too weary-looking to wear in public. For this reason I keep things I really like "for best". I just can't be bothered replacing them very often.
