Lost navy blue floor-length evening gown with intricate beadwork near Kenai Peninsula wedding venue.

I lost my navy blue evening gown while attending a wedding at a venue near the Kenai Peninsula last weekend. I remember taking it off to go for a dance and then couldn't find it after leaving the dance floor. It’s floor-length, with intricate beadwork around the bodice, and has been a favorite in my formal wear collection. If anyone has any information or has found it, I would be very grateful to get it back.
