Emerald green beaded gown found near Hyannis

I found a floor-length emerald green gown with gold beading along the neckline, folded on a chair in the parking lot behind the Cape Cod Mall in Hyannis last Friday around 6:15 pm. It's a women's size M, with a satin ribbon belt and a tiny seashell charm pinned to the zipper pull. Inside, the tag says 'Lina's Bridal, size M' and there's a small monogram 'A.R.' on the lining. The fabric looks pristine, just a bit wrinkled from being carried. This seems like something special, and I’m hoping to help the owner get it back before their event. If this matches yours, message me with distinguishing details.
