My mother made mine - it was very pretty and stylish at the time. Donated it about 12 months later as I knew I wouldn't alter it to use for another occasion and thought someone else may as well get some use out of it while it was still fashionable.
I'm not sentimental about clothes. Getting married was the important part to me - not what I wore.
My daughter was married not that long ago. She would not have worn it in a fit (times have changed) even if I had saved it.
