I have found that having enough clean clothes (underwear, socks etc.) for at least a month makes for fewer loads of laundry because I do a full load and can time it for the weather since I hang everything on the clothes line. Have for nearly 50 years. I did have a dryer when my son was a baby for when I could not get diapers done and dried fast enough... and sometimes used it for when I was working 2 jobs and needed the waitressing clothes to be done quickly and ready... but always hung clothes out when I possibly could. The dryer has been in the storage shed for the last 10-12 years.
I also have at least 5 pr jeans and a multitude of button down or snap shirts with 2 pockets for work.... being by myself makes less loads but full ones... and it is worth the time to hang and save all that electricity... and they SMELL SO GOOD when you bring them in.
