The 29-year-old 'Roar' singer favours bright colours and playful stage costumes by brands like Moschino and Cavalli during her 'Prismatic World Tour' because she still has the same fun-loving sense of style she had when she was a teenage girl, reported LifeStyle magazine.
"There's a lot of colour in my shows. I have so much fun with it. I'm going to be 30 at the end of this year, but I still feel like a 13 year old. Right now, I'm really obsessed with the Versace early 90s soft-grunge look, but I don't think there should be any rules when it comes to colour," Perry said.
Despite being on stage almost every night during her world tour, Perry ensures she does at least 30 minutes of cardio per day.
"When I'm on tour, the exercise routine is vigorous. I'll work out every day, and I don't have time for a full hour of exercise, I'll run on the treadmill for 30 minutes. I actually love having that uninterrupted time to listen to new music or my favourite albums, and it feels great to get the blood circulating, too," she said.
