Will a wool sweater after it is washed shrink or get stretched?
How often should I wash my wool sweater?
Wool sweaters do not need to be washed as often as other types of clothing. In fact, it is best to wash them as infrequently as possible, as frequent washing can cause the fibers to break down and the sweater to lose its shape. Generally, you should only wash your wool sweater when it becomes visibly soiled or stained.
