The assumption here is that clothes are being thrown away because they are worn out.
Except that’s not why the majority of clothes are thrown away. The real reason they are thrown away is because of size changes and fashionability.
HN probably has an over representation of the types of people who wear out clothes and even here it’s likely a minority that actually do wear out clothes.
GLP-1's solve this, now you're basically only losing weight and eventually (i.e. the 2030s) most people won't fluctuate much in weight. So, try again on "changing sizes". Yes I'm aware that children grow up rapidly and need new clothes. Don't buy goodyear welted boots for your 7 year old.
The best fashion is timeless, and that's why heritage fashion is far superior to trends. Coincidentally, it's why the brands I listed above are exclusively heritage brands, who have basically no regards for trends.
There's a reason HN is poorly dressed. I'd rather take the "only dresses with startup T-shirt" guy over the "I've gotta have the Sydney Sweeney Jeans" person, and especially over the sneakerhead crowd which now thinks Hoka and NB is superior to Nike.
