Most company will store your wedding gown in a card board box. Many use treated acid-free or PH balanced cardboard and tissue paper for your gown. However, even acid-free or PH balanced cardboard boxes can re-acidify over time, often in three to five years. This is why costume conservators and museum curators recommend replacing these boxes periodically to ensure the proper long-term archival preservation of valuable textiles such as wedding gowns. Additionally cardboard storage boxes take a lot of space and must be handled with care. Store the box flat, with top side facing up. When you move the box, make sure it is totally level when you carry it so that your gown does not shift. Check the box for mold and mildew every few years, as they may harm your gown. If you live by the beach or otherwise a high humidity area, check the interior of the box often for mold and mildew as they can ruin your gown.

According to experts, curators and The Smithsonian Institution in Washington, DC., a sealed cardboard container absorbs and can trap moisture that may promote the growth of mold or mildew within the storage chamber. This will stain and weaken the fibers of your gown as it affects even clean fabrics. Professional textile curators always recommend that a fabric be allowed to "breathe". In fact, neither the First Ladies' Gowns nor presidential upholstered furniture nor even "Old Glory" (the "Star Spangled Banner" flag from 1814) are in air-tight or sealed rooms. Yet, they are beautifully preserved.(latin gown,dance gown)
