1940`s Slipper Satin Wedding Dress

I have my mothers wedding dress from 1940. It is a slipper satin dress, long sleeves with satin buttons from end of sleeve to elbow. Also has stain buttons all the way down the back of the dress. Sweatheart neckline fitted to just past the waist in a V. Very long train with full skirt. I have a picture of my mother in the dress if you would like to see it. Needs to be cleaned and has been in storage for some time. No stains of any kind that I can see. I would estimate the dress to be worth about $1000.00.
