RARE Ludovic de Saint Sernin dress

Very rare designer gown. Crystal embellished mousseline maxi dress. Would best fit a 4 or a small 6. The crystal embellishments are beautiful, simple but edgy. This gown is right off the runway. If it were a little bigger I wouldn’t give it up for anything. Hard to find photos of it, if you would like a video of it let me know.
