What should I wear for an interview?

-What should I wear for a Jewel Osco grocery bagger interview?As a grocery bagger I would just dress nice, no tie or anything, but look nice like casual pants and nice shirt .... collar or just nice shirt is fine imo. Imagine you are interviewing them, what do you want to see? Dress as if you are someone that takes the job seriously as thats what they want.Probably a shirt (& Tie is optional) and tailored trousers - a dress suit would be too much - jeans n tee shirt is a big nono?
