Navy satin evening gown with crystal belt

I lost my navy satin Calvin Klein evening gown, size 6, yesterday around 3pm near the Starbucks on Central Ave in Old Town Albuquerque. It's a formal wear piece with a detachable silver crystal belt and a slight crease from folding in a bag. The inside lining has my initials 'VS' embroidered in silver thread, a small detail that helps identify it. It was a gift from my grandmother and still holds sentimental value; I wore it to my sister's wedding last month, and I’m really hoping to get it back. If you found it, please drop me a line at [email protected].
