I love when this comes up and also I see it play out in my life, where my GF prefers fast fashion whereas I buy something from brands I like and I wear it for long (some of the clothes in my wardrobe have been there for 12+ years.. I feel old.)
Also Sir Terry Pratchett is a gem of an author and you should read all of his books. I have read through maybe 25% of Discworld and it's the funniest fantasy series ever.
I do the same (wear clothing for a long time) but I only buy the cheap stuff. I bought 1 replacement shirt in the last 5 years and 1 bag of replacement socks in the same time frame.
I wanted to like Discworld and read a couple of the books but they're frankly not funny.
This has stuck with me for years.

“Yeah,” said Rincewind, picking up a knife and testing its blade thoughtfully. “Luters, I expect.”
