Gay men had less facial hair, suggesting differences in androgenic hair growth, grooming style, or both. They also had lighter skin, suggesting potential differences in grooming, sun exposure, and/or testosterone levels. Lesbians tended to useless eye makeup, had darker hair, and wore less revealing clothes (note the higher neckline), indicating less gender-typical grooming and style. Furthermore, although women tend to smile more in general (Halberstadt, Hayes, & Pike, 1988), lesbians smiled less than their heterosexual counterparts. Additionally, consistent with the association between baseball caps and masculinity in American culture (Skerski, 2011), heterosexual men and lesbians tended to wear baseball caps (see the shadow on their foreheads; this was also confirmed by a manual inspection of individual images).
