We're used to seeing some fun-loving Instagram pics from the Delevingne sisters, but none beat those posted by Cara Delevingne and older sister Poppy after their recent attendance at The Animal Ball in St James Palace, London.
Hosted by the Elephant Family, a charity dedicated to protecting the Asian elephant, the lavish masked ball enlisted the help of fashion and design greats to help raise money and enjoy a star-studded event.

Both sisters took advantage of social media to show off just how eventful the ball was as they mixed with members of the royal family which included Prince Charles and the Duchess of Cornwall.
Our favourite Instagram addition definitely has to be Cara Delevingne's rather unusual video of a masked badger and mouse having a dance-off, while Cara pulls a cheeky face for the camera.

Not to be left out, Poppy added a pic of the sisterly pair posing, comically captioned: "Babes in the wood" - tagging the designer friends responsible for their stylish ensembles, with Poppy in a sequinned Dolce and Gabbana shift dress while Cara opted for a dramatic cut-out black Burberry gown.

Their accessories however were the real talking point, as Poppy chose a flamboyant golden feathered mask from Giles Deacon to match her gilded dress, leaving Cara to up the fashion ante in a smouldering black plaited leather eye mask and leather whip.
