Topshop Unique Live event will get online followers involved with Topshop's London Fashion Week show.
You’ll be able to customise the clothes from the Topshop Spring Summer 2013 fashion collection as they come down the runway on 16 September.
The high street fashion brand has worked with Facebook to develop a special camera button. It'll let us take pictures of the show’s live stream as if we were sitting in the front row!
We'll be able to change the colour of accessories and clothes, share our designs with friends and then order pieces instantly.
Not only that, Topshop Twitter followers can win VIP tickets to the next show by reviewing the Spring Summer 2013 runway in 140 characters! Plus to top it all off, the show’s music will be available to buy on iTunes.
