What is it that they say? That the clothes make the man?
Well, while I don't believe that clothes have any bearing on your competence as a professional, I think we can all agree that appearances do matter. As a general rule, people will treat the well-dressed and well-groomed better, and looking your best can provide a big confidence boost. So, it's important to have an elegant, polished look at work, to make the most of your time at the office and maximize your chances of success.
