Katy Perry is thankful for the time she saves by wearing Velcro clothing.The Firework singer plans to stip off in super fast time during her California Dreams world tour - and says layering up with Velcro outfits is the best way to go about it.

"I just found out that I will probably be changing between 15 and 20 times in the show," said Perry. "I’ve done a lot of changes before so I think I can handle it.

"The trick is to have clothes underneath clothes, underneath clothes, underneath clothes. And it’s all about Velcro - it was such a saving grace."
