Today is red
Today, tomorrow and the day after, red is the colour of your clothing. Red as a colour makes you more attractive. Ever since the Romans, the colour red has been seen as a status symbol; it was the most powerful men who clad themselves in red. Psychologically, red has a dominant effect on the observer. And women apparently like to be dominated by powerful men. It's not for nothing that many politicians wear red; it simply makes them a good deal more attractive.
A relaxed stubble beard
According to various studies, men with a ten-day beard are the most attractive. In short, no beard is so 2017. No, this year we're going for a nonchalant look. Stubble makes you look more mature and more masculine, which women in turn get a kick out of.
Attitude
It's all in your posture; good posture works wonders. It makes you look slimmer, taller and healthier, and that's logically attractive. And keep things serious. Men who don't smile are rated as more attractive by women. This, like so many things, in contrast to women, who are actually found more attractive by men when they do smile. Research shows that a poker face looks mysterious and masculine. And that's something women like.
Pump it up
Women aren't very clear on this… When you're looking for a long-term relationship, muscle mass isn't a requirement for women. But for a night of fun, women do specifically look for men with a bit more muscle mass. In short, let's pump it up, gentlemen! After all, everyone prefers something with a bit of shape to it ;-).
The George Clooney effect
Where men think 'the younger the better,' women really do often fall for older men. Is this also about rich men — I can see Hugh Hefner coming to mind ;-). Old men (seem to) hold more wisdom. They've had more time to develop themselves and often have, there it is after all, more wealth.
