Lost & found formal wear in Essex

Lost black slim fit tuxedo jacket with satin lapel, possibly left at the coat check area of Essex Manor during a wedding.

I lost my black tuxedo jacket while attending a wedding at the Essex Manor last Saturday. I believe I might have left it in the coat check area, but I'm not entirely sure. The jacket is a slim fit and has a satin lapel. It's quite special to me, as it was a gift from my parents for my first formal event. If anyone finds it, I'd really appreciate getting it back.
