Dîner en Blanc is a worldwide event in which people have a meal dressed in white in a temporary dining setup in a public space. The event began in Paris in 1988 when François Pasquier invited a group of friends to an elegant outdoor dinner at the Bois de Boulogne, asking them to dress in white so they could find each other. The events presence has grown to over 90 cities, with almost 17,000 gathering for the 30th-anniversary event in Paris. Diners are required to provide their own food, tables, chairs, and tablecloths. The event is organized by Dîner en Blanc International, which is responsible for developing this secret posh picnic in close to 80 cities in 30 countries around the world.

The event is known for its elegance and glamour, and guests engage with one another, knowing that they are taking part in a truly magical experience. The event site must remain a secret until right before the event starts, and guests are required to wear only white, not cream, and no shorts. Only wine and champagne should be served, a nod to the first Dîner en Blanc in Paris in 1988. The event typically includes a three-course meal of appetizer, entrée, and dessert, and guests may bring their own food or purchase catered meals on the Dîner en Blanc online store.

In summary, Dîner en Blanc is a unique and elegant event that takes place in public spaces around the world. Guests dress in white and bring their own food and dining supplies to enjoy a magical evening with others.
