Navy blue Calvin Klein gown with silver belt

Hi, I lost my navy blue satin evening gown yesterday around 4pm outside the Moscow Food Co-op on Main Street. It's a floor-length gown, size M, by Calvin Klein, with a slim silver belt and a small run along the left hem near the zipper. The fabric has a slight sheen and the dress is otherwise in good condition. It was a gift from my sister and has sentimental value, and I'm really hoping to get it back before the weekend formal. If you found it or saw someone leaving it, please email [email protected] with any details.
