I'm about to go to an interview for a part time job at Waitrose, and I'm not really sure what to wear. Every other interview I've been to has been for something like bar work and I got the job just wearing what I normally wear. I've decided on smart blue shirt, black trousers and belt and some black shoes. Over dressed? I might start going out like this actually, I think I look alright.

But yeah, I could substitute the shirt for a plaid one or something I dunno?
