It has been ages since I had clothes shrink on me. To the point that I had assumed something must have gotten better in modern dryers. Is that not the case? Edit: Quickly searching, this appears to be the case? Specifically modern moisture sensing dryers that stop appropriately goes a long way to never having something shrink on you.
I think a lot of things use pre-shrunk fabric these days. I've got t-shirts that haven't shrunk, and t-shirts that have. Unfortunately a lot of band shirts bought at concerts fall into the latter :(.
Even cheap band t-shirts don't shrink in our dryer. I have sweaters that I am confident would have shrunk in the past, but do just fine here.
On that last, I almost forgot I had direct evidence. We visited a place that shrank some of our clothes that we had washed many times back home.
