Hey guys.
I have an interview next Friday for an internal job position.
I don't own a suit...

I know, right.
Anyway. I intend to buy one and am looking at the traditional grey or navy suit.
My question is - shoes. I have black, tan, dark brown, grey and oxblood. I am leaning more towards a navy suit with either a plain white / light blue shirt and a plain red tie or a gingham shirt that's navy and red chequered (very small squares) and again, the solid red or navy tie. This is something I will play about with once I have the suit to see which I feel more comfortable in / looks better to me.
I just don't know what to do shoe wise. Out of all of the choices above, what do you think would pair better?
I could probably make the decision myself by trying it all on etc, but I wondered if there were any basics I should know when it comes to wearing suits given I haven't really worn one before.
The article Matt did last year on here was very helpful but shoes were not mentioned and I wondered if anyone could throw some advice my way?!
Oh, suit selection by the way is this bad boy:

Again, if anyone thinks this is totally wrong - please tell me! I intend to dress it up a lot more than the way this dude is wearin it haha.
Cheers in advance.
