After taking my Mom's lace gown out of the box (it was preserved over 30 years ago) and seeing how the years had not been kind to it, I decided to donate one of them to the breast cancer society gown sale. I am not sure if they have one near you, but I feel at least some other bride will get to enjoy a gown while the money from its sale goes to a good cause.
I have also heard of people taking the material (leftovers from alterations, etc.) and making pillow cases and such.
