If an item isn’t soiled or visibly dirty just freshen it up, whenever possible, leave garments open to the elements, or hang them up in a well-ventilated area so that air can circulate and any moisture evaporates before you wear them again. If you do this, they should stay clean longer and you'll need to wash them less often.
Treat stains as soon as you can.
Wash the garment when you feel that the freshness has left.
