I'm looking for a white outfit for the upcoming Le Dîner en Blanc event on October 7th, 2017. What is Dîner en Blanc? Most people have never heard of exclusive soiree because it's the city's kept secret. It's a little like Fight Club, you'll have to find a way to get an invitation to attend but without the violence of course.And you know what the first rule of Fight Club is? The first rule of Fight Club is that you never talk about Fight Club. It's the same with Dîner en Blanc.
