Taupe queen duvet cover set with navy piping

I lost my taupe queen duvet cover set with navy piping yesterday around 3pm. It was last seen in Ventura County, near the Ventura Harbor Village outside the Fisherman’s Wharf area along Main Street, behind the old warehouse by the bike racks. The set includes a queen duvet cover and two matching shams. The fabric is soft cotton sateen, in decent condition, but there’s a small coffee stain on the inner flap and the zipper pull on the duvet cover has a tiny blue bead I tied to it. My initials 'MF' are embroidered in the inner corner. It really has sentimental value — it was a gift from my grandmother, and I’d be incredibly grateful to have it back when possible.
