This is what I wore to a job interview for a receptionist position at a salon and spa. On top I wore a chiffon dress shirt with an over sized blazer. I decided to dress the outfit down a little by wearing jeans because the job is not ultra professional; black skinny jeans are both causal and chic so they work. The pumps work because they are a professional height, around 3-3.5 inches with a .5 inch platform. I kept my hair, makeup, and accessories very simple.
