Serpentine Summer Party: All The Pictures

The Serpentine Summer Party is one of the most-awaited events in the London Social calendar. The annual soirée is always host to glamourous VIP guests in gorgeous party frocks. See who spent a balmy evening at The Serpentine's biggest event...

The Serpentine Summer Party is the soirée to kick off a series of swanky summertime festivities around London. Swarming with celebrity guests in elegant looks, The Serpentine Gallery in Hyde Park holds the shindig annually, making it one of the hottest events on the VIP calendar.

Straight from Glastonbury Festival, Alexa Chung ditched the wellies and went with cool Christopher Kane at the glamorous summer party.

The stylish event is always the place for super-stylish A-listers like Kate Hudson and Naomie Harris - to mingle, discuss the gallery's latest exhibition and share secrets to looking flawless on the red carpet.

And couples are also very welcome, too. Hollywood actor Ewan McGregor made an unexpected appearance with his equally stylish wife.

Models-of-the-moment Suki and Immy Waterhouse seemed to be the hottest sister duo of the night and looked to be having plenty of fun, wearing incredible mint green creations.

The fashion set were also out in force at the Serpentine's summer bash, including Karlie Kloss, Charlotte Dellal and Poppy Delevingne.

So if it's some summer style inspiration you're looking for, you're sure to find it here.
