Katy Perry California Dream tour costume from Part of Me on display...

To help promote Katy Perry's behind-the-scenes documentary movie Part of Me, ArcLight Hollywood cinema had this candy confection of a costume from the pop singer's California Dream concert tour on display in its foyer on June 30, 2012.

The outfit created by Erin Lareau is worn on stage by the pop star on her recent world tour and featured in the Part of Me movie, which chronicles the singer's life on and off stage. I think it's also the costume featured in the mirror image billboard for the movie too.

UPDATED: If you're a Katy Perry fan, then you'll also enjoy this stage costume the singer wore at the Hollywood Palladium in 2009.

This short silver sequin dress with its pink ruffle was photographed on display in the window of the Hard Rock Cafe along Hollywood Boulevard on January 6, 2015.
