Diner en Blanc, Paris

When Francois Pasquier came up with the idea to host a picnic with friends and dress up in white to find each other, he had no idea it would become an international phenomenon.
Now in its 26th year, Diner en Blanc -- a flash mob concept in which people dress up head to toe in their most elegant white frock and transform a public space into a restaurant terrace -- has been exported to 40 cities worldwide.
