In the clothing wearing behaviour, complexed relationships have been found between human preference among clothing styles and human personality traits. This study has mainly focused on relationships of college women students' preference among clothing styles and their personality traits. The following four specific interpretations have been inferred from the results: (1) An extravert personality trait negatively correlates characteristics of fashion preference era (degree of out of fashion, or degree of classic) and styleness (degree of decorativeness, or degree of unbalanceness) . Positively correlates with emotionalism (degree of romanticism, or degree of luxuriousness) . (2) Emotion-stable personality trait positively correlates with emotionalism of the style preference and negatively correlates with the restraint of style, i.e., degree of gap between the style of clothing which students usually wear and style of clothings which they desire to wear if possible. (3) Society-adaptable personality trait negatively correlates with restraint of style. (4) The degree of restraint of style positively correlates with characteristic of the fashion preference era.
