The cost to have your gown cleaned varies, depending on the type of dress, how much fabric is involved, the type of stains and other factors. Although you can do your own packing and storing, it's advisable to have a professional preserve your gown. Silica gel is normally added to absorb any moisture. Store the box in a cool, dry atmosphere away from sunlight, heat and humidity. Do not store in an attic or basement.
Attic heat can produce yellowing and basement dampness can cause mildew.
Experts suggest inspecting your gown every year or so and refolding it along different lines to help prevent permanent creases. When inspecting your dress, you may want to wear cotton gloves so that oil or dirt from your skin doesn't stain the gown.
