I've just been using the same brand of socks for ~15 years 🤷♂️ I just get like one pack every year and have never had to match anything since. I also have never understood the fancy-/patterned-sock craze, so that's a non-issue.
I've been using the same couple packs of the same sock for almost ten years I think. I never walk in them without shoes, wash on delicate, have fine some really minor repairs on two or three socks, and they still look fine. Just regular puma socks, I dunno why they have lasted so long. It makes me unreasonably happy NOT to buy new clothes.
