How often do you dry clean your jacket? Not as often as you might think. But that doesn't mean they don't require maintenance. Unless a jacket is visibly stained, it probably shouldn't be dry cleaned more than twice a year, provided it is well looked after. This involves keeping it neatly folded on a proper hanger, hanging it up where it can air for 24 hours after you wear it, not wearing it more than once a week, brushing it with a clothes brush, and storing it in a place with enough closet space.
