Navy Adrianna Papell gown with pearl neckline

I lost my navy blue Adrianna Papell evening gown, size 6, yesterday around 7pm. It's a floor-length satin dress with a pearl-embellished neckline and a subtle side slit. The gown is in good condition overall, no stains, but there is a tiny snag along the hem from a crowded reception. Inside the lining there's a small pink satin ribbon with my initials 'KP' stitched in. It was a gift from my grandmother and has huge sentimental value—I'm really hoping to get it back if anyone found it near the Augusta Mall on Wrightsboro Road yesterday evening.
