That's truly bizarre. I genuinely can't imagine what could have physically caused that. Like, if that happened to me I'd have to assume a family member had warm-washed and machine-dried the shirt without telling me.

You can have your own opinions on quality -- if there's anything I know, people have been complaining about the decline of quality of major brands every year for as long as I've been alive. Yet somehow clothes still seem fine. But that's actually irrelevant.

Because the point is, there aren't really any conceivable fabric quality issues that should cause a cotton-spandex shirt to shrink with a cold wash and hang dry. It doesn't matter the brand or quality, that's just not how cotton or spandex work. And even if you do accidentally wash warm once or dry, the denser weave that a dress shirt has will always shrink less than something like a looser Oxford or a t-shirt jersey material. So even just one warm wash on a dress shirt shouldn't have a huge effect.

So truly that's just bizarre. I have no explanation.
