At the 2010 MTV Movie Awards, Katy wore the wig soft, polished and Pin-up inspired with a sparkly mini dress.
At the 2010 Kids Choice Awards, Katy wore it ombre and paired it with a matching yellow and blue minidress (seen here presenting with Jonah Hill).
Why wear it twice? When you've got a good thing going, why not take advantage?! Plus, a great synthetic costume wig will last multiple wearings if you take care of it. Her blue wig is Pin-up Girl meets Superhero! Rock that costume wig, Katy.
