Black sequin evening gown, champagne accents, size 8

I lost my black evening gown (formal wear) with champagne sequin accents yesterday around 3pm near Coligny Plaza on Pope Avenue in Hilton Head. It's a floor-length Adrianna Papell gown, size 8, in good condition except for a tiny, nearly invisible tear along the left hem and a detachable satin bow at the waist. The dress is black with champagne sequins along the bodice and hem, and it has a flowing train that caught the light nicely. It was a gift from my grandmother and meant a lot to me after her passing, worn to a family wedding last weekend. If found, please email [email protected] — I really need it back for a wedding this weekend.
