I agree with the budget friendly dark suit. In addition, keep your jewelry simple and conservative. One pair of earrings regardless of the number of holes you have, a watch or bracelet is acceptable. One ring(set) per hand (including wedding ring). Don't forget to smile and be courteous to EVERYONE you meet from the time you step out of your car at your interview site. 😎 That should have you ready in the attire department. I personally did not carry a purse to my interview. I had a small leather bound notebook to make notes about each interview and interviewer so I would know what to say in my thank you notes to help them remember me. It was cold during my interview, so a placed my keys in my coat pocket
