Singer's also inspired by pin-up girls and Lolita
The 24-year-old star admits she’s a big fan of dressing up.
‘I’ve always experimented with clothes and have my own style inspired by pin-up girls and Lolita,’ she says.
‘I love to create a character, and I like looking like I’ve just stepped out of a history book.’
Katy changed her outfit 12 times while hosting the MTV Europe Music Awards in November 2008.
