Suit, or "business professional" attire?

I'm sure this is a common question that has been asked a lot. I've read up on this topic on other online forums, but they were not nursing-forums. Of course, wearing a suit is the obvious choice when interviewing for positions such as banking, accounting, law etc. Everything I've read in terms of nursing-interview attire seems to have split opinions. Half say that wearing a suit is ideal, and shows respect for your interviewer as well as the hospital/company. It also shows respect for yourself and conveys a high level of professionalism. While I undoubtedly agree with all of this information, I also agree with the contrary opinions/ advice. Some posts said that if you are an entry level or new grad nurse (which I am), you can easily get away with wearing professional business attire e.g. a Navy Blue Blazer with a dress shirt & tie and Khaki/ tan dress pants. Some say that a suit may be seen as, "too much" or excessive, and the latter option of business professional attire is better. As this is a nursing forum, full of experienced opinions, can you guys please guide me in the right direction as to what the best options are? I received an interview offer for an ER Fellowship program, and I have accepted the interview, I just have not been given the available interview dates from HR, yet.
