Dîner en Blanc

Started more than 25 years ago in Paris, Dîner en Blanc is an impromptu picnic now held in dozens of public spaces throughout the world each year. Event organizers ask guests to dress in all-white clothing and bring a list of items, including white plastic folding chairs and tables, white tablecloths and napkins, and white dinnerware.
