Determinants of physical attractiveness were investigated in a study employing U.S. college students of both genders. Five factors were derived from a study of 37 stable and changeable physical features: Masculinity (strength, larger body and chest, broader chin), Femininity (longer hair, make-up, larger and rounder eyes), Self-care (overall grooming, shapely figure, flat stomach, erect posture, fitted clothes), Pleasantness (friendly, happy, babyish face), and Ethnicity. Factor analytic results did not support a priori (and nonstatistical) groupings of babyish facial features by investigators who use this concept. Self-care, Masculinity (Femininity), and Pleasantness were positive correlates of male (female) attractiveness. Attractiveness was described parsimoniously in terms of emotions: more attractive targets elicited more pleasure, more arousal, and less dominance (or more submissiveness) from others. Men and women reacted in essentially similar ways in rating others' attractiveness. Statistical tests showed that emotional reactions mediated relations of the independent variables (physical features) to the dependent variables (judgments of attractiveness).The present study was designed to investigate effects of most physical features previously shown to be determinants of physical attractiveness. Findings from studies conducted primarily with college students in the United States helped delineate the physical features to be explored.Physical correlates of attractiveness have been categorized as static (or stable) and fluctuating (or changeable) features (Brown, Cash, & Noles, 1986). "Static" features included relatively enduring physical characteristics such as height or eye color. "Fluctuating" or changeable features referred to characteristics that varied over time, such as hair style or facial pleasantness.Body shape has been found to be an important stable determinant of attractiveness. Shapeliness of physique related to ratings of attractiveness in men and women. Women preferred men exhibiting V-shaped bodies (Lavrakas, 1975). Also, upper body strength enhanced ratings of male attractiveness (Franzoi & Herzog, 1987). In comparison, men favored women with hourglass figures (Gitter et al., 1983).
