I doubt Uniqlo clothes last five years while tumble dried. I hand dry the few t-shirts I own from them and after three years I wouldn’t wear them as anything else than bed wear.
When I used to wear business casual, I wore Next brand clothing and shirts/trousers looked the same to me even after years of drying and cleaning them. The part that starts showing wear is the fold in the collar, but that only happens a long time after I have gotten my $20 or $30 worth.
I am sure there are some visual differences between top tier clothes and what I wear, but I am okay with it as long as what I have looks clean and presentable.
