It takes a few seconds, according to Albert Mehrabian (1972), to a person form opinions about the other (opinions regarding social class, personality, level of success and self-confidence, etc.), it is known as first impressions. This happens because personal appearance elements are communicated even before verbal words. Personal appearance, according to Knapp (1999), is one among many ways of nonverbal communication, and with the help of its elements, such as clothing, posture, color, hair, height, beauty, and even odor, it is possible to convey coherence and/or disagreement in communication. This article aims, by use of bibliographic reviews of studies and scientific articles, to reflect on the meaning of personal appearance in nonverbal communication and how some of its elements influence impressions caused. It starts from the assumption that the image of personal appearance can influence others. it extends from a theoretical investigation about personal appearance elements communication and their influence on impressions caused.
