Lost & found casual wear in Devon & Cornwall

Lost blue silk evening gown with lace detailing near a hotel outside Newquay, Cornwall.

I lost a beautiful blue silk evening gown while attending a wedding in a hotel just outside of Newquay, Cornwall. It has a fitted bodice and a long flowing skirt, with delicate lace detailing on the shoulders. I realized it was missing as I was packing up after the event, and I've been desperately searching everywhere since. If anyone has found it, I'd really appreciate its return!
