How to dress for a job interview at McDonald's?

Job interview later on. I want to dress nice but does this sound okay?

• Hello! I'm 19 and I've been looking for a job for a really long time, I was talking to a friend and he let me know how well he was doing in his job, he told me he works for an insurance company and I let him know how happy I was for him because he was earning so well while studying and working part time, I let him know I have had so much trouble finding a job and that I hope he keeps doing so well with his current one. Well surprisingly he spoke to his boss about me and she called me, she told me she wants me to go in tonight for an interview, she says my friend spoke wonders about me and that she'd like to meet me. I still don't really know what the job's really about, my friend was vague when he said he worked for an insurance company, but anyway I want to know how can I dress? She told me to dress casual, so that makes it easy I guess. But should I stress it a little more and work on looking a little more than simple? The interview's at 7:30 tonight, I have a few more hours, but I wanted to know would jeans & sweater be okay? She said casual so I don't really know or what to wear. I know it's not appearance the only thing that matters but I'd at least like to look well and presentable. I'm a female...I'll be wearing my hair loose since I had it done.

• Answer:

  its good.dont wear casual.they need to see you care about getting the job
