Serpentine Summer Sunset

You can do yoga in some most unusual places in this city of ours, but this is the first class we've seen in an outdoor art installation. Athletic apparel brand Lululemon are hosting the free session at the Serpentine Pavilion's spaceship-like installation. Arrive from 6.30pm for a 7.30pm start as it's first come, first mat. Drinks and canapés will follow the class, just to make the whole evening a tiny bit more surreal.
