Your focusing too much on a suit and less on what will actually get you the job. An experienced interviewer is going to look beyond the suit and may have a profile setup in his mind of what he wants. What will get you a job is simply attitude and presentation. Dont bother wasting your cash on a good suit. Go out and spend a few dollars on a book like Knock Em Dead and figure out the real way to get that job. I can bet you that a person with the right attitude will get that job over you in a suit purchased from Target or Walmart versus you in the 3000 dollar suit. You have the wrong priorities is my observation.
