Interview Attire - What extent to dress like a banker

Then you probably shouldn't wear it. Old Rule of Thumb. Think conservative garb with a slightly modern appeal.

Don't miss the point. Your interviewer won't hire you because you're wearing a Hermes or Ferragamo tie or have a tailored suit. They can pick any chappie off the street if they just need to look like a banker. People have been hired into BB wearing stuff that you would never see a banker wear - based on impressing their interviewers.

I agree with vadremc - try not to stick out too much with the way you dress - you might be unlucky and get some annoying interviewer who will try to make it count against you).

very conservative dress - white/light blue shirt and no cufflinks, charcoal or dark navy suit and a conservative tie - you can wear Hermes or what have you, but just make its not too "colorful"

YES stay conservative, not cuff links, solid color tie, white shirt black suit and shoes is the way to go. i just had an interview at a hedge fund and that is what i wore
