Your dress may have noticeable stains from food or make-up, or the hemline may be soiled. Or your dress may look clean to you, but don’t be fooled, spills from alcoholic beverages or clear soda may dry clear, but oxidize with time, turn brown and become more difficult to remove later. Body perspiration may cause the dress lining to turn brittle over time. Your dress needs to be cleaned in order to keep it in the best condition possible.
