When we were kids, I think wearing hand-me-downs was just normal for just about everyone. We weren't poor. My dad was a federal government bureaucrat, and a fairly senior one. But in my case boy clothes would start with my big brother, move to my older cousin, come back to me, and then on to my younger cousin if they were still serviceable.
Mom and all the moms of my friends had a basket of clothes, including socks, that needed mending. When they'd get a chance to take a break and sit down, they'd do the mending. Fixing socks was called "darning."
So kids and adults would wear clothes with obvious mends and no one thought it odd. On the other hand, we all had our "Sunday best" to wear to church, too. And dad wore nice suits to the office.
(I workd in NYC , when I was 19, with a Japanese war bride in a retail store. She must have been in her forties by then. She told me the story of how early in her marriage she was mending her husband's torn shirt and he asked her what she was doing. When she explained, he laughed, and said to throw it away, that they'd just buy a new one. Made quite an impression on her. It just seemed such an amazing practice to her.)
