Navy blue satin evening gown with silver belt

I lost my navy blue satin evening gown yesterday around 3pm near the Northpark Mall entrance on Range Line Road in Joplin. It's a Calvin Klein gown, size 6, full-length, with a detachable silver beaded belt that catches the light; the fabric has a subtle sheen. There’s a tiny bead missing from the neckline and a faint snag along the hem that you might not notice unless you're looking closely. This gown has sentimental value—it was a gift from my grandmother and I wore it to my cousin’s wedding last summer; I really need it back. If you’ve seen it, you can reach me at [email protected].
