It's likely that a more mature woman will already own a wide assortment of clothing and household items. Because their tastes are pretty well defined, it is best to steer clear of buying a Christmas gift that will gather dust on the shelf, or worse yet, be returned. A planned outing together can be a wonderful way to show you care; buy theater tickets or a restaurant gift certificate and set the date for spending some quality time together. Another good idea would be to enroll her in a gift-of-the-month club.
