Many of the strategies that women use to signal their sexual interest in men are subtle and nonverbal, such as eye contact, eyebrow flashing, open body posture, and smiling. Although men are more likely to use overt strategies, such as initiating conversation, men often wait to receive women’s signals before "making their move". Researchers posit that women use more subtle sexual signals because they may want to avoid a reputation for promiscuity, or because they may want more time to evaluate a man's quality as a potential mate or interest in them. Similarly, women may underestimate their own interest in men due to concerns over sexual double standards. Because women tend to use subtle cues to signal sexual interest, men who are more sensitive to these covert cues may have more successful dating outcomes.
While it is true that women may dress in sexier clothing to signal sexual interest, that signal may only be meant for attractive men, or it may only be directed toward one man in particular. Therefore, clothing is not a reliable indicator of women's sexual interest in men in general. Furthermore, men also seem to use women’s physical attractiveness as an indicator of sexual interest, assuming that women who are more attractive are also more interested in sex. Women's physical attractiveness is unlikely to be related to their interest in men in general, and women who are very attractive may even be less interested in sex with most men. Men who have been trained to ignore signals, such as clothing and physical attractiveness, and focus on women’s emotional expression tend to more accurately perceive women’s sexual interest in laboratory experiments.
