Years ago, maybe '70s or '80s, an ad ran in Mother Earth News magazine for a kind of dress/wrap that could be worn in several ways. You could dress it up or dress it down, just by wearing it in different ways. There was something timeless in the look that made me think that it would never go "out of style." I'd think that that kind of design, along with durable fabric, would make clothes last a long time.
Would love to find that ad again!
