Katy Perry is a style chameleon and adapts her fashion sense to fit the occasion. At the Nickelodeon Kids Choice Awards, she wore a neon outfit. But for an after party at the Coachella music festival she went for a more subdued color palette and an indie rocker look, wearing hipster-favorite brands Wildfox Couture, House of Holland, and T.U.K. You can buy Katy’s Wildfox Couture White Label The West Was Won Hankshaw Dress for $399.00 or $445.00, House of Holland for Pretty Polly Bones Tights for £12.48, and T.U.K. A7270 Creeper Shoes for $65.00.

Katy Perry has dyed her hair ginger! I’m really not a fan of this look, but luckily it’s only temporary. Katy was intending to go for a different color – she wouldn’t reveal which, but because her hair had been black, she ran into some difficulties and will have to keep it ginger for a little while before proceeding. She tweeted:

tonight I dye my hair a different color… Can you guess which color?!

So I didn’t get to the exact color I wanted from being black for so long! 2get to goal I have 2b GINGER for 3WKS #paybackfromGINGERGodsFML!

If I don’t wait 3wks, I’ll end up w/no hair or a #pixie90scutw/abarretteinthefront It’s okay, I’ll get to my secret color(s) soon! #patience
