If neither of the two options fit within your budget, you have one last choice remaining: DIY. The first step is to choose a trustworthy dry cleaner and have your wedding dresses and bridal accessories cleaned. Do this within six months of your wedding at the most. Once you get back your wedding gown, remove all the plastic. Fold the wedding gown. Take acid free tissue paper or unbleached muslin and place between folds. Wrap the entire dress in the muslin and place in an acid-free box. Store the box in a dry, dark place. Avoid places with high humidity or high temperature swings. You will also need to air the wedding gown at least once a year. Also, refold the dress along different lines so that creases don?t develop.
