Ivory ballroom gown with crystal belt, size M

I lost my ivory ballroom gown with a crystal belt yesterday around 7pm near the Clemens Center on Main Street in Elmira. It's a floor-length satin dress, size M, with a detachable crystal belt that catches the light. There are tiny pearl buttons along the back and a faint coffee stain on the inner lining near the zipper—mostly unnoticed when worn. The gown is in good condition overall, just a bit wrinkled from being stowed in a garment bag for a week. This dress means a lot to me; it was a gift from my aunt and I hoped to wear it to a fundraiser this weekend. If anyone found it, I’d be incredibly grateful to get it back.
