Katy Perry at the Jean-Charles de Castelbajac Ready-To-Wear Autumn/Winter 2011/2012 show in Paris on March 8.
There are many things jockeying for our attention in Katy's ensemble (those Ray-Ban Clubmasters are very omnomnom), but the thing we heart most desperately is the INCREDIBLE Jean-Charles de Castelbajac fan. It's like The Dude's rug. Really ties the room together and is super easy to DIY. And by DIY, we mean, buy it and/or wait until some enterprising soul
rips it off renders an homage.
