Based on a study done here, having pearlie white teeth is a universally attractive feature. 

The research found that uneven coloured teeth is often less attractive. Instead, people in general tend to prefer naturally white teeth, with just a little bit of imperfection. 

Research has found that red is a universally attractive colour and it tends to catch the eye of a lot of people. 

The research above also shows that men don’t actually know that they’re attracted to the shade! 

This New Zealand research paper revealed that men prefer women with a bigger waist-to-hip ratio. 

However, that’s not to say that you should worry about it if your body isn’t curvy! 

Join the no makeup selfie movement because according to this study from the Quarterly Journal of Psychology, people prefer it when women wear less makeup. The study reported that when contestants (men and women) were shown photos of women wearing less makeup, they preferred it more than women who were using plenty of it. 

Blondes may have more fun but brunettes are wayyyyy more attractive — according to this study in 2008. 

Finally, ladies, no matter what these studies may have mentioned, women everywhere are beautiful no matter their hair colour and shape.
