Dressing differently is not necessarily dressing worse. Personally, when I see someone that obviously spent an extra 30-60 minutes getting ready in the morning to make themselves appear to be a professional, my first impression isn't "This guy is really professional". Instead, it is "what is this guy trying to hide?", or "does this guy think appearances are more important than results?" You really shouldn't assume you're making a good first impression because you're wearing a tie. It all depends on what the atmosphere of the workplace is.
