Help! What should i wear to my job interview at a cinema?

i got an interview at a movie cinema. i'm a girl but i don't know what to wear to it! i have been thinking about going in a cardigan with blue jeans , pretty much my casual outfits. i been doing some research and some say that you should NEVER wear jeans, and some are saying that it's a casual job and it's okay to turn up in jeans. but i have no idea. help please!
