I never understand the underwear ads or how people are supposed to feel sexually charged in front of pictures of models, boys or girls. I honestly think they are all ugly.
Here is my beauty standard:
There are certain pleasant features that require symmetry. Like how rule of thirds in photography will often look more pleasant than randomness. But rule of thirds is very common and easy.
Then there is effort on how to carry themselves. Less about what they wear. But more about healthiness. And being comfortable but polite.
Passing those 2 and you are considered good-looking. However, I don't drool over you no matter how much healthier you can be or if you want to maximize on your golden ratio. I don't even call you attractive because I'm not attracted to you. AT ALL. However, I can say, “You have a symmetric face”.
Then you reveal your personality and I love your personality then you are the most attractive person.
In case I find out you being inauthentic then you don't stay in good-looking. You go back to being ugly again.
