Katy Perry launched her new fragrance Killer Queen in Berlin on Wednesday.
The global superstar wore a red and black pleated tartan skirt and matching jacket to the event. To finish off her schoolgirl look Katie opted for over-the-knee black socks, black boots and wore her hair up in plaits.
The 28-year-old looked confident and was happy to smile for the cameras whilst posing with her new fragrance.
The Teenage Dream singer left the press conference in style, jumping on the back of a motorbike before being driven off by a leather-clad driver.
