The Westfield London Fashion Detector is a neat tool created by the mall to tell you where to find what that woman walking down the street got her top. Or where your friend of a friend you are stalking on Facebook got her beautiful off-white dress.
The fashion detector works on your computer and on your mobile phone. Their campaign argues that clothes look better on real people than on mannequins. They are taking advantage of the fact that what people are wearing is free advertising. The Westfield London Fashion Detector is brilliant, I dare say, brilliant.
