Lost black tuxedo jacket with satin lapel, size medium, at Utica-Rome-Oneida Fairgrounds during a wedding.

I lost my black tuxedo jacket while attending a wedding at the Utica-Rome-Oneida Fairgrounds last Saturday. It has a satin lapel and size medium tags. If anyone happens to find it, I would really appreciate having it returned as it holds a lot of sentimental value to me.
