Pitching in on promotions for her new fragrance, Katy Perry arrived at the Douglas Perfume Store in Berlin, Germany on Wednesday (September 25).

The “Roar” singer donned a school girl-inspired ensemble as she showed off her Killer Queen collection to her overseas fan base.

Upon her arrival, Miss Perry tweeted, “Oh hay Berlin!”

Meanwhile, Katy continues to promote her high school giveaway, where one lucky student base will win a special performance from the star.

Today she reminded her fans to enter, sharing, “Have the ROARING spirit?! U still have 6 days to enter the #GMA ROAR contest for me to come play YOUR high school.”
