Midnight blue evening gown, size 8

I lost my midnight blue Adrianna Papell evening gown yesterday around 3pm, somewhere along Market Street in downtown Center, TX, in Deep East Texas. It's a floor-length satin dress, size 8, with a silver beaded waist belt and matching delicate straps. There is a tiny snag on the left hem from a curb and a small loose thread behind the zipper in the lining, which are pretty distinctive. It was a gift from my grandmother and means a lot to me; I would really appreciate getting it back for an upcoming gala.
