Lost elegant black tuxedo jacket with inside pocket containing card holder at Joplin Convention Center during a wedding reception.

I lost my elegant black tuxedo jacket while attending a wedding at the Joplin Convention Center last Saturday. It has a sleek design and an inside pocket that contains a card holder. I believe I left it on a chair during the reception when I went outside for some fresh air. I've been searching everywhere and would greatly appreciate if anyone has seen it!
