Calvin Klein navy tuxedo jacket, size M

I lost my Calvin Klein navy tuxedo jacket, size M, yesterday around 3pm after the charity gala at the Emerson Center for the Arts & Culture on West Main Street in Bozeman. It's a navy tux with satin lapels and a slim cut; inside pocket has a tiny silver crest and a monogram 'AH' on the lining. There's a small coffee stain on the left cuff and a slight snag in the right pocket lining, but it's otherwise in good condition. This jacket was a gift from my dad and carries real sentimental value, so I’d really appreciate if someone found it.
