We know it's summer when the creme de la creme of British style hit Hyde Park for the big Serpentine Summer Party! As well as being treated to a live performance by Pharrell Williams, guests enjoyed a DJ set by Keira Knightley's hubby James Righton and lots of food and drinks. Not a bad Tuesday night, eh?
