The problem with clothes is that unless you maintain exactly the same weight over your whole life typically you will need different sizing. Also you have to understand your use compared to others. There is no mileage on a shirt or pants. So you have no idea how it was used. I know with my cheap clothes I don't really care and will just throw them in the washer and dryer. Where as with a something more expensive I will hang it to dry or hand wash it. Typically, you will take care of something more if you paid more for it. And then there is how much you wear that thing. Your work pants might get more use then a pair of expensive dress pants so they just wear faster. That doesn't mean that they are better just that you didn't wear them as much.

Use patterns matter massively. And not everyone is the same. I run so I go through running shoes every 6-12 months. There is no running shoe I can buy that will really last longer than that. If instead I wore them only once every couple weeks they will last far longer in time. So when you see someone who wants running shoes to last for life I understand that isn't possible for me regardless of what I buy.
