I am lucky if my kids wear only one set of clothes a day frankly. As soon as they are back at school, that's already one set of uniform, one set of clothes, one set of pjs a day. It takes no time to put in the washing machine.
I tend to wear jeans and jumpers a couple of times before putting them in the wash, but as soon as you take public transport, or cook, or just go for a walk at this time of year, things get dirty or smelly and need to be washed.
That's why I don't wear my work clothes at home, I have cheaper clothes that are easily washed and low maintenance.
I don't wash my towels after every use, because they don't smell or feel dirty.
I don't really care what other people do, and care even less about their possible judgements on my washing habits, it's none of their business.
I can't go to bed without having a shower first either.
