What are some associations we have with the color red? Passion, roses, heat, and…sex. For this very reason, science has shown that wearing red is one way how to look more attractive. “This red-attractiveness link is partially explained by men’s perceptions of implied sexual receptivity among women wearing reddish garb,” Dr. Beall says. “In 2013, my colleagues and I even noted this effect among a small-scale society in Burkina Faso, West Africa, suggesting that men’s attraction to red is a cultural universal.” So no matter where you’re living, if you’re looking for love, red should be your go-to color. And you might even be doing this subconsciously—Dr. Beall says studies have shown women tend to wear red and pink when they are biologically more sexually receptive, like during ovulation.

Don’t play hard to get
Women might think they appear more attractive if they keep their partner guessing as to how they really feel—and some research does support this (one study from China found that playing hard to get kept men’s interest only after they had chosen a prospective partner). But a more recent study from Germany suggests that people are more likely to rate others as attractive if they can easily understand the emotions they’re displaying. The reason for this is in the brain: How well the study participants could decode the other’s “neural vocabulary.” “Partners must understand and continuously update information about their partner’s current intentions and motivation, anticipate the other’s behavior, and adapt their own behavior accordingly,” study author Silke Anders, a neuroscientist at the University of Lübeck, told Time. “Understanding and personal attraction seem to depend on both the sender’s brain and the perceiver’s brain, and on how well they match.” A dating expert gives eight ways to meet and attract new people.
Speak in a higher pitched voice for women, lower for men
Ladies, think that smoky voice sounds sexy? You might want to think again. Research from the U.K. has found that a higher-pitched voice in women is more attractive to men—and vice versa, that a lower-pitched voice in men is more attractive to women. “Past work suggests a higher voice pitch is perceived as coming from someone who is physically smaller in terms of body size,” Dr. Beall says. “Gender dimorphic—in other words, typically feminine—qualities such as these have been shown to increase men’s sexual attraction to women.” (Need to know how to be more articulate?

But in the U.K. study, breathiness in men as well as in women was considered attractive, which the authors say may be because it softened the aggressiveness associated with a large body size.
