"A picture is worth a thousand words." The effort that an individual devotes to their appearance does communicate to certain audiences your attention to detail, discipline, etc... in ways that a silver tongue alone won't. We can argue over the accuracy/applicability of any conclusions drawn from that, but in certain domains/problem spaces appearance is a very relevant assessment tool in building trust.
