When is it appropriate to wear Business Professional to a job interview?

When I was pursuing the job I currently have, I did overdress for my job interview. While I was in a suit, he and both of the other interviewers were in polo shirts. I had to be picked up, since the interview location was access controlled, on the way to the interview location, riding with the manager, I asked if I should wear my jacket. He told me it was not necessary. I went sans jacket, but still with button up shirt and tie. I out dressed them all, and after the interview, while I was introduced to most of the rest of the team that I was joining, I noticed that not a single one wore a tie. The normal attire was business casual. I overdressed, but I was able to modify on the fly, and the manager may have even seen that as a positive trait. Be prepared, but also be flexible.

I've always tried to at least wear the level of attire worn by the employee that is working the position I am applying for. When I applied for my electrician position, I wore a nice shirt, pants, and tie. Felt really overdressed. However, I did get the job. Really though, at the least, look your best (clean and presentable). For example, my last gave-to-face was on my normal work day at my old job and the interviewer set the interview for after my shift. I just made sure I cleaned up.
The lead manager, at my location, has said it's all how the applicant presents themself, not, as much, what they look like.
