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.

Warm vs cold water usage,

dryer settings,

local environment in the laundry room.

Probably in that order.
