Abstract: A hat retention device and ornamental jewelry apparatus is disclosed. The apparatus includes a necklace and a leash formed of a material and design similar or complimentary to the ornamental design of the necklace. First and second connectors are carried on opposite ends of the leash and are selectively attachable to a hat worn on the head of a wearer and to the necklace. The leash functions to maintain the hat in close proximity to the wearer in the event that the hat is separated from the head of the wearer; providing an ornamental appearance complementary to the design of the necklace.
