Cream duvet cover with blue piping, King size

Lost my cream duvet cover with blue piping yesterday around 3pm after packing up at the Market Street entrance of the Charleston City Market. It's a king-size duvet cover, 100% cotton, with navy piping along the edges and a tiny navy monogram 'KP' embroidered in the bottom left corner. There's a faint coffee stain near the inner seam from a camping trip last month, but it's otherwise in good condition. I think I left it near the Market Street side of the city market building, maybe tucked into a tote bag or dropped on the sidewalk outside the cafe by the entrance. It has sentimental value—my grandmother gave it to me—and I really need it back.
