"Although dark personality traits are linked to negative relationship outcomes, people who are high in the dark triad tend to be rated by others as more physically attractive."

While red pillers seem to omit dark triad traits being linked to bad relationship outcomes, they have a history of bringing up the research that Dark triad types are rated as more attractive (this is one of the foundations of red pill), and thus think by emulating dark triad traits, they will be more attractive to women.

A recent study took a deeper look into this and asked "is it the case that people with dark personalities are naturally more attractive, or do they manipulate aspects of their appearance to enhance their attractiveness?"

"To answer this question, researchers had peer group raters assess participants’ physical attractiveness in two different states: an adorned state (i.e., the participant dressed and looked how he or she typically looks and dresses in public), and a natural state (i.e., the participant wore a gray t-shirt and sweatpants, no makeup or styled hair, and no extra adornments such as jewelry). The researchers were interested in effective adornment, or the degree to which people do things to enhance their appearance beyond their natural attractiveness (such as groom their hair, wear makeup or dress in stylish or fitted clothing), and whether this was related to specific personality traits (as rated by the participant and raters from their peer group).4 In other words, the researchers were interested in whether attractiveness ratings for people high in the dark triad were based on their natural attractiveness or their appearance-enhancement efforts."

"It turns out that people with dark personalities are not naturally more attractive, but instead they do more to enhance their appearance, such as dressing and grooming in ways that make them appear more attractive. For example, women with a dark personality might wear more make-up, style their hair and dress provocatively; men with a dark personality might groom their facial hair and wear expensive clothes or accessories. People with dark personalities may get boosts in self-esteem from being noticed for their appearance or may attempt to enhance their appearance to attract sexual partners."

There was -.11 correlation (i.e. slight negative correlation) between dark triad traits and peer rated unadorned attractiveness, and .23 correlation between dark triad traits and peer rated effective adorned attractiveness. So dark triad types only were rated as more attractive in adorned states.

And contrary to red pill claims Agreeableness (kindness, consideration) positively correlated .21 with peer rated unadorned attractiveness (keep in mind people were rating just based on looks, they didn't know the personality scores of the people they were rating).
