Lost black medium tuxedo jacket with satin lapels and white handkerchief pocket square near the Belle of Louisville during a wedding.

I lost my black tuxedo jacket during a wedding ceremony held near the Belle of Louisville last Saturday evening. It's a size medium with satin lapels and a white handkerchief pocket square. I briefly took it off when we were taking group photos, and when I looked for it afterward, it was gone. I'd really appreciate any help in getting it back!
