I went to the Martin Margiela 20 Year Anniversary Exhibition today at Summerset House. It was only £5 for a student and was pretty amazing.
There is loads to see, like this caravan which is at the entrance.
Inside there are tons of clothes, videos and images to look at. One of the rooms shows you the interiors of some of the shops around the world and explains why everything is painted white. To find out why you will have to go and see. I tried to take pictures but i had hangover shakes and the staff were pretty fascist when it came to having my phone out. Its on till September 5th.
