When you bring you clothing home from the dry cleaners, DO NOT keep them in the plastic bag. If you need to keep them covered until next season, use an old pillow case instead (cut a hole int the top so the hanger can poke through). A pillowcase can breathe unlike the plastic bag so it doesn’t hold mildew-causing moisture. The plastic bags can also cause discoloration. If you want to reuse them, use them as car trunk liners.
