Kiki's Delivery Service is a japanese animation film from studio Ghibli written, directed and produced by Hayao Miyazaki in 1989, it is based in a novel by Eiko Kadono.
It's basically the story of Kiki, a 13 year old witch that has to go live a year alone in another city as part of a tradition. She works in a bakery running the delivery service (you didn't see that coming huh?) and the main plot is her struggle during her adventure alone.
As I do with the movie cards I get here's the english trailer:
