Katy Perry's Arthur Premiere Look

Katy Perry joined hubby Russell Brand at the London premiere of his new film Arthur on April 19.  

Quite a demure look from Katy in a nude, floor-length design from the Fall 2011 collection of Philip Armstrong.

Without a doubt, Katy looks nice but the modest color, make-up and simple accessories make this quite lackluster for her.  A great look for just about anyone else but Katy's problem is expect something a little more from her.
