I know you are not supposed to dry it in a machine but I can’t have a t shirt I don’t dry with the rest of my clothes. I am inbetween a L and XL in American shirts, and I know the XL normal cotton t shirt shrinks too much after drying. I tried this hoping the XL would shrink to be “perfect” since it’s wider… but no I was wrong. They seem to shrink “up” and turn into belly shirts. Oh well lesson learned. For me, 5’7.5 and 200lbs I need to get and XXL and let it shrink to fit me.
