On June 13, 2020, thousands of friends and neighbors will gather on the Park’s scenic Peninsula for Prospect Park Soiree. Guests are encouraged to wear their most festive attire, including show-stopping toppers—fabulous hat and headpieces to celebrate Prospect Park. We dug into the Prospect Park Alliance Archives to find some hat inspiration!

At the Centennial celebration in 1966, this reveler makes the case for a simple straw boater.
