We've had pistachio eyebrows at Balenciaga, moustaches at Vivienne Westwood, and neon hair extensions at Ashish. So it was only a matter of time before some wild and krayzee young thang (Ke$ha) decided to give the Hannah Marshall AW2010 trend for blue lips a go. Hell, she went the whole hog and upped her fashion stripes with some arm paint too. While she looks very pleased with herself (and a bit of a hot mess if we're honest) will you be dabbling in blue hues?
