It seems that the appearance of women is very subjective for the opposite sex: some men like plump women, some men prefer thin girls, and others don't want to know about the shape, but pay attention to other things.
Scientists have come to the conclusion that there are many things about the external appearance of women that men notice unconsciously.
Find a summary of all the data that scientists collected and that reveal the most important things that attract men extremely.
1- Voice and way of speaking

Marilyn Monroe is a great example of the ideal voice. The least attractive voice is a booming voice like Kim Kardashian. This is because high female voices are associated with youth, which equates to attractiveness. Another research showed that men prefer women who speak in a similar way to them. This has to do with the way certain words and letters are pronounced, the rhythm of the speech and other details.
2- Length

Probably everyone knows that most people prefer shorter women than themselves. The difference in height can be less than 20 cm. However, there are many men whose height is less than average. So while tall men try to find short women, short men look for women of a similar height.
3- Age

Scientists found that men between the ages of 20 and 30 prefer women between 24 and 25 as partners. This is because in this period a woman is likely to become a mother. And in this case, it does not matter whether a man or a woman still thinks about children. It's all because of evolution. Men who are older than 30 and choose older women cannot be explained by this theory. Perhaps, in this case, we should look for more psychological reasons and motivations, or perhaps we should keep in mind the fact that there are no situations where men choose women based only on a criterion of attractiveness.
4- Eye color

Scientists from the University of Tromso, in Norway claim that blue-eyed men prefer blue-eyed women. Or that brown and green-eyed men don't tend to prefer blue-eyed women.
5- Makeup

The study claims that men prefer women who use cosmetics in moderation. The strangest thing is that women don't really want to wear very bright makeup, but they think men like it, so they often do it.
6- Waist-hip ratio

Cary Fitzgerald, a psychologist from the University of South Carolina in Beaufort, and her colleagues conducted a study and concluded that men memorize better women who have an ideal "waist-to-hip" ratio. Such women are considered more attractive. According to research, the ideal waist-to-hip ratio is approximately 0.7. According to experts, models such as Kate Moss and Kelly Brook and actresses such as Marilyn Monroe and Jessica Alba have the ideal waist-to-hip ratio, despite the fact that they have completely different body shapes.
7- Limbal ring

The eye color aspect may not be very clear, but the limbal rings are very straightforward. The limbal ring is the dark ring around the iris. Scientists have come to the conclusion that wide, prominent rings attract men more.
8- Hair color

Scientists have conducted research that shows which women are invited to dance in nightclubs more often: those with blonde hair, brown hair or red hair. The conclusion was that men invite blondes more often than others. Second place was taken by brunettes, and red-haired women were less attractive to men.
9- The length of the legs

Men prefer women with longer legs. This statement does not contradict the part of men who like short women. Men like the fact that a woman's legs are long compared to her body.
10- Curved middle

The curvature of the waist is another universal standard of female beauty that has been fixed in the male brain thanks to evolution. On average, the angle between the back and the buttocks should be about 45.5°. This curvature is considered to be more attractive to men. This is because in the past (as it is now) this curvature allowed women to avoid back pain during pregnancy. Of course, many pregnant women experience back pain, but women who don't have the "correct curve" seem to be more susceptible to back pain. You should always keep in mind that looks are not the only thing men care about. There is also inner beauty and we strongly believe that every woman is attractive in her own unique way.
