Officially, that's my first pool party I went this summer.
Even I was in France, that party was organized by Americans. It's call Day&Night, they threw the party at Stefano's Forever, it's a pool club in St.Tropez.
This event is run by the coolest twins around called Derek and Daniel who do the best brunch parties in New York. They also have a restaurant in NY called MPD. Their St.Tropez launch was nothing but spectacular! Great people, amazing food and very good music... all the New York "faces" they were there!
