Late to the party as well but I would like to mention that I always try to dress appropriately for the job I?m interviewing for.

I have actually seen people who were passed over for basically coming in to an interview overdressed.

For example, if I were interviewing for a position in the oil or gas industry I would likely just wear nice jeans, good shoes or boots, and probably a nice polo shirt. Unless you were applying for a position in upper management, a suit and tie might give the impression that you might not be a good fit.

Office type work and I would think nice slacks and a nice dress shirt should suffice.
