Black velvet evening gown with silver beading

I lost my black velvet evening gown last Saturday around 7pm. It's a floor-length gown, size 6, by Calvin Klein, with a deep V-neck and a row of silver beading along the neckline and down the sleeves. There's a small satin bow at the waist and a faint coffee stain on the inside hem from getting dressed earlier. It was left outside the Broward Center for the Performing Arts on SW 5th Ave, Fort Lauderdale, near the valet area, before I headed to a rehearsal. It has sentimental value—it was a gift from my grandmother—and I really need it back. If anyone found it, please reach out; I'll be forever grateful.
