Lost black evening gown with unique lace detailing along the neckline and a long flowing skirt at the reception area in Daytona Beach.

I lost my beautiful black evening gown while attending a wedding in Daytona Beach last weekend. It has unique lace detailing along the neckline and a long flowing skirt. I remember putting it down at the reception area to take some photos, and when I went to grab it later, it was gone. It holds sentimental value, and I'd really appreciate any help in finding it.
