Yes completely agree. I always hang up my washing (also in NZ, don't have a dryer) and was recently sorting through my tshirts as we are moving country. I have one t-shirt that is nearly 20 years old and still holds its shape (though the color and print has faded) on the other hand i threw away a bunch of other t shirts which were just over a year old because they developed holes and particularly the collar is completely broken. Funnily their color and print is mostly fine.

I don't think brand is a good predictor either, e.g. the old t shirt is from threadless IIRC while I had many other threadless tshirts which didn't last near as long.
