6. Red-clad men.
When shopping for something to wear to the club, you probably know to skip the Ed Hardy. But a study in the Journal of Experimental Psychology: General found that even more than a sense of humor, women are attracted to guys in red. The concept was pretty simple: participants ranked photos of people based on their desire to kiss or date them, as well as overall likeability. When just looking at these sex and romance-related factors, researchers found that guys in red scored higher. (No similar effect was seen in men looking at photos of women.) The finding held true across disparate cultures from Japan to the States, and researchers attribute it to the perception of red as a marker of high status. Our theory? Deep down, all women love the Kool-Aid Man.
