Katy Perry and that ubiquitous blue 'do have been taking Paris Fashion Week by storm.
After donning a daringly sheer Vera Wang number and then a flashy, short Balmain mini to Karl Lagerfeld's Hogan fete, Katy took a ladylike turn for the Viktor & Rolf show.
Approaching the Espace Ephemere Tuileries on Saturday, Perry posed in a royal blue cutout Viktor & Rolf coat layered over a coordinating black dress. There were also blue tights, that blue hair and a Christian Louboutin blue "pill" purse involved. That Katy loves to color coordinate...
While the whole ensemble was signature Katy theatrics, it did remind us of Jennifer Lawrence, who wore a pared-down dress from the same Viktor & Rolf collection at the 2012 People's Choice Awards. Lawrence, of course, kept her natural hair color for the event.
