Before marriage, love or even a meeting, there is attraction, the unexpected force that brings two people together. Physical attractiveness refers to physical traits that are perceived and considered aesthetic or beautiful. There are several factors that cause a person to be attracted to another. These factors can vary across many cultures, cultural and social aspects, and individual subjective preferences (Gangestad and Scyheyd, 2005). An individual's perceived attractiveness can have a significant effect on how he or she is judged in terms of employment or social opportunities, friendship, sexual behavior, and marriage (Townsend & Levy, 1990). The media and the general public portray a woman's sexuality as a mystery, but is it? Scientific research has revealed several factors that influence heterosexual women's attraction to men. Researchers have shown that women are strongly attracted to men who are pleasant (Jensen-Campbell, Graziano and West, 1995), intelligent (Hatfield and Sprecher, 1995), full of humor (Bressler, Martin and Balshine, 2006), generous (Sprecher). & Regan, 2002), a high level of income and social status are also key factors in partner selection (Townsend & Levy, 1990). The majority of women are attracted to symmetrical faces with masculine qualities such as a prominent chin and cheekbones as well as a symmetrical, muscular body, with shoulders wider than the hips (Gangestad & Scyheyd, 2005). Women also prefer a slightly taller than average man with a deep voice (Buss, 2008). The combination of these traits is linked to good health and high levels of testosterone, which increases the chances of reproduction (Gangestad and Scheyd, 2005).

Compared to fake smiles, an individual's cheeks are more activated, which causes the orbicularis oculi muscles to contract. oculi, displaying crow's feet wrinkles in the corners of the eyes. eyes (Hager and Ekman, 1985). There is evidence that people unconsciously check for crow's feet to determine whether a smile is genuine (Williams, Senior, David, Loughland, & Gordon, 2001). Other studies have found that fake smiles elicit less trust in first impressions than real smiles (Averbeck & Duchaine, 2009). The aim of our experiment is to explore the effects of the type of smile: real or fake, and the background color: red or white. on an individual's perceived attractiveness based on their sexual preference. Based on previous research and experience, we hypothesize that models with real smiles and a red background will be perceived and evaluated as more attractive..
