What outfit would be good for an interview for an office job?

Hi, I’m a female in my early twenties. I’ve only had a few interviews, and I would always wear the same outfit. That outfit is a blue blazer with a nice white top under it, but I would never get hired. I don’t have a lot of professional clothing since most of my work experience is working at restaurants. I have another interview coming up and I’m wondering what would be a good interview outfit for a female?
