Job Interview Questions: How should I dress for a job interview at target?

I have a job interview at Target for a cart attendant on Friday.I pretty much know what I am going to say for most of the questions they ask me, but I don't know what to wear. So any ideas?
I thought just a dress shirt dress pants and dress shoes but i don't know if that's too much?
I have a polo shirt what could I wear for pants and shoes?
any advise?
