Clothing is considered part of your overall appearance. Being primarily a visual species (that is to say visual until we became thinkers who considered character as part of base appeal) we judge one another on overall appearance. If your overall appearance is slovenly, people will judge you as lazy and apathetic. If your appearance is foreign to them, people will see you as, well, foreign to their mindset. If your appearance is recognizable and neat, people will see you approachable and reliable.

Don't you wish we all were blind?
