One of the most interesting things you can ask in a store with high-end clothing is "Which of your items are most likely to last a hundred years?" There's a special joy that arises between you and the shopkeeper as the veil of bullshit disappears and they tell you up front that 95% of the clothes they sell are disposable name-brand garbage made overseas, but THIS item, typically made of denim, or wool, or leather, has been made in the same place in the same way for a century, and they see customers come in wearing their 50-year old article regularly.
Of course it's much easier to buy this year's model of something hyped & shiny without thinking and then post on a site like this to prop up your ego and mislead everybody else. I'd venture to say that if something hasn't been in production for the length of a lifetime, there's no justification in labeling it as "Buy it for life"
