Tan Panama hat with black ribbon, sentimental

I lost my tan Brixton Panama hat yesterday around 3pm in South Beach, near Ocean Drive and 10th Street. It's a Brixton Panama hat woven tightly, one-size-fits-most, with a thin black ribbon and a tiny coffee stain on the underside of the brim. Inside, there's a small leather patch with my initials 'AH' stitched in. The brim has a slight bend from a fall into a palm tree, and it's sentimental because it was a gift from my grandmother who loved summer styling. If anyone found it, I’d be incredibly grateful to get it back—it's hard to replace.
