On Saturday afternoon Katy arrived at the Viktor & Rolf fall runway show wearing an electric blue techno silk duchesse coat over a black and blue dress from the designing duo's S/S 2012 collection.
The Part of Me songstress finished off her look with black tights, blue Casadei pumps and a Christian Louboutin pill clutch.
What do U think of all the blue??
