Navy tuxedo jacket lost in downtown Klamath Falls

I lost my navy blue Calvin Klein tuxedo jacket yesterday around 3pm near the downtown library on Main Street in Klamath Falls. It’s a size M, with satin silver lapels and a classic two-button closure. The inside lining has a small coffee stain near the left pocket, and there’s a subtle silver monogram 'LN' along the inside cuff. The jacket is in decent condition overall, though one cuff button is loose. It means a lot to me—it was a gift from my grandfather, and I really need it back for an upcoming family gala.
