It sounds like you have a great plan for your washing, it sounds like mine as well. Your story reminded me of my daughter. When she was living at home and in H.S. she would always everyday throw everything she wore into the laundry. I also told her she could get more wear out of a pair of jeans than once. That yes always change her underwear and socks and since she sweat a lot to always have her shirts and sweaters in the laundry as well. Now that she is on her own she tells me she understands why she didn't need to wash her jeans everyday. :) She doesn't really like washing and drying them either. lol. My jeans can even go longer than 2 days if you are like me. A homemaker and don't get out all the much so they don't even get a chance to get dirty. But in the Summer I am outside a lot and I am working in the flower beds, working with our dogs and mowing grass, I get very dirty then. I go through a lot of shorts and shirts. :) and several showers a day since I exercise a lot as well. I walk in the mornings, so I need a shower after.. I work outside all day, get filty, need another shower... then I walk again or use the treadmill and weights, get all sweaty, hense.. another shower. Not only does our water bill go up in the Summer but so does my ironing. lol. I do dry most of our stuff outside though. That helps.
Take care and have a great day.
