Business casual attire
Business, or at least smart casual. at the end of the day your going to a interview, impress.
This was for experience but I have to wear black t-shirt and pants to represent the company. I was interview at the phone calls.
Something nice casual, possibly clothes from target to show that you have shopped there and are interested in getting a job there.
