Abstract
Similarity attraction is a robust phenomenon related to interpersonal attraction. Previous studies have focused primarily on similarities in attitudes or personalities. We experimentally examined the effects of similarities in clothing and makeup on interpersonal attraction. Undergraduate women (n = 41) participated in Study 1, which experimentally demonstrated that similarities in makeup enhanced interpersonal attraction. Undergraduate women (n = 47) participated in Study 2, which experimentally showed that similarities in clothing increased interpersonal attraction, whereas identical clothing was less attractive than similar clothing. These results suggest that similarities in clothing and makeup could enhance attraction at people’s first-meetings and promote relationships. However, contrary to the prediction of the similarity attraction theory, identical clothes might decrease interpersonal attraction by interfering with the satisfaction of uniqueness needs. We have discussed the limitations and future directions of this research.
