Emerald-green satin gown with gold embroidery

I lost my emerald-green satin evening gown yesterday around 7:15pm near the Forsyth Park fountain on Drayton Street in Savannah. It’s a floor-length gown, size M, with subtle gold embroidery along the neckline and bodice, a delicate side slit, and a hidden inner pocket. The fabric is a bit worn from the night’s dancing, but it felt priceless because it was a gift from my grandmother and I wore it to my cousin's wedding. Inside the lining there’s a small fabric tag with the initials 'KP' and a tiny blue ribbon someone might have tucked back in the pocket during the night. If anyone found it, I’d really appreciate getting it back.
