The Firework singer, who is famed for her penchant for quirky, colourful clothes, said she wants to enjoy fashion while she’s young.
Perry told People: “They [clothes] have an expiration date and that’s why I’m wearing them now at 25. I’m such a sucker for a theme, so if I go somewhere like Vegas, I’ll dress like Vegas! Or if it’s Christmas time, I’ll dress like Mrs. Claus! '
She added: 'I think sometimes with the themed stuff … ’I won’t be wearing that to get my Starbucks today. Although maybe my whipped cream bra I’ll wear, because I’ll help [the baristas] out. ‘I got it! I got it! Hold the cream! No worries'.”
The star, who married British comedian Russell Brand last month, added she’s been fashion-conscious ever since she was a littlie.
“I’ve always been girly … even though I was a tomboy. My mother said when I was a kid, I was changing for breakfast, lunch and dinner. I don’t make it a big deal, I just do it.”
