Lost elegant black tuxedo jacket with satin lapel and red stitching inside pocket in Knoxville at a formal event.

I lost my elegant black tuxedo jacket while I was at a formal event in Knoxville last Saturday evening. I remember taking it off as I got a bit hot during the dinner, and I think I left it on a chair. It's a size medium and has a satin lapel with a small red stitching detail on the inside pocket. If anyone finds it, I'd really appreciate getting it back, as it's my go-to for special occasions!
