Do less laundry

. Many items of clothing, such as jeans and sweaters, don’t need to be washed every time you wear them. Try to be aware of which items of clothing are truly dirty and which could be worn again. This will not only save water, but will save wear and tear on your clothes![15]
It’s normal to wear pajamas two or three times before having to wash them, especially if you shower before going to bed.
Do change socks and underwear daily, but wear slacks, jeans, and skirts more than once between washings.
When wearing a sweatshirt or sweater over another shirt, you only need to wash the innermost layer regularly.
Hang towels on a rack to air dry after you shower, and use them multiple times between washings.
