Here's what you need to know from the show....

1. Vivienne Westwood is angry, very angry. Anyone who has seen her catwalk shows over the last couple of years know that they have involved some sort of anti-establishment demonstration. This season was no different, Vivienne invited her model army and activist friends to open the show with a demonstration aptly titled Fash Mob, about fracking, anti-austerity, climate revolution and political corruption. Even Westwood herself waved a placard before the show, staging a protest outside the venue.

2. Instead of using a traditional soundtrack, the show opened with police sirens followed a voice chanting on repeat, 'Hashtag, hashtag, Twitter, Instagram; wake up and hashtag, go crazy every day.' The irony wasn’t lost on the audience, who were all taking pictures on their phones throughout the show to share on social media.

3. It's always a worry when a designer chooses to stage a political performance that the clothes become secondary to their agenda, but this was a shoppable collection, with look after look showcasing Westwood's greatest hits. Of course, with her punk heritage, no collection is complete without Tartan, but this time it came in its traditional cotton and also in a great metallic print lame which she dotted through the collection. Watch out for the metallic print trend that we have already spotted so much this season. Another ELLE favourite was the rose-printed lace and also the insect-jewel-encrusted lemon dress.

4. The protest theme also followed through to make-up. The girls had oily black shadow smeared over the eyes, looking like anarchic Mad Max-esque antiheroes.

5. The event was a star-studded affair: Alice Dellal, Lili Sumner and Lizzy Jagger stalked the catwalk, while Lily Allen, Foxes, Dree Hemmingway, Phoebe Collings-James, Sadie Frost lined the front row.
