Your suit should be tailored, fit well and free from obvious creases and ideally dry cleaned regularly. Shoes should be polished.

I know I sound a bit crazy, but impressions really do matter and various studies indicate that many people will judge you based on apperance more than what you are actually saying. The message here is don't give them any reason to be distracted by what your wearing or not wearing, that way they will focus more on what you're saying.

But on the flip side of that, you have guys like Richard Branson who famously don't wear suits.

To each their own, in my opinion though tech / IT guys look lazy when they just dress casually.
