What do men notice when they look at a woman's body

Woman's body has evolved as a permanent, portable sexual signalling system which is purpose-built to attract male attention for reproduction and bums, breasts and legs play the most significant part in this process. This may not be politically correct, but it is biologically correct.
The woman has always been defined as the symbol of beauty. But will the hair, breasts, hands, or make up to make it really so attractive? Then we discover it together like a man when he sees a woman walking down the street, and what annoys me just the women.

Bums

Men find rounded, peach-shaped buttocks the most attractive. A human female bum differ from other primates in that other primate females display enlarged, protruding buttocks only when they are ready for mating. Human females display enlarged buttocks permanently and are almost always sexually available to males. This is because one of the main purposes of regular human sexual activity is to encourage long-term pair-bonding for the successful rearing of children.
Humans are the only primates that mate face-to-face in other primate species; the males approach females from the rear and use her swollen red buttocks as a signal that she's ready for mating. And therein lies the key to men's attraction to women's bums, they always give the impression that she's available for him which helps answer "what do men find attractive in women?"
Women's bums also have two other purposes: they store fat for breastfeeding and act as emergency food storage in lean times, similar to a camel's hump.

Wearing designer jeans has also become popular because they highlight the buttocks and give them a firm, rounded look. High-heeled shoes make the wearer arch her back, push out her bum, and make her wiggle when she walks, which invariably draws male attention. Marilyn Monroe reputedly chopped three-quarters of an inch (2cm) off the heel of her left shoe to emphasise her wiggle. The females of several species of beetle also wiggle their rears in front of potential mates to attract attention. What all this boils down to is that bums are the favourite of what men find attractive in women. 
Boobs

Most of the world has developed an obsession with breasts in recent years and cleavage and cosmetic breast enhancement is now a multi-billion pound business. This is remarkable considering that human breasts are little more than enlarged sweat glands.
Most of the breast consists of fat tissue. This gives them their rounded shape and most of this tissue is not involved in milk production.
Overall, breasts serve one clear purpose — sexual signalling. Breasts mimic a woman's rear view — a relic from the days when humans walked on all fours. If a monkey or chimp walked towards you on two legs you'd be unable to tell whether it was male or female. Humans walk upright on two legs and enlarged female breasts evolved as a mimic of the female rear. Tests conducted with pictures of bum cracks and breast cleavage convincingly shows that most men are unable to differentiate one crack from the other.

Low-cut dresses and push-up bras emphasise this signal by creating cleavage. Fortunately, nearly all sex research surveys show that men love breasts in most shapes and sizes - it's the cleavage that stimulates men the most. It doesn't matter whether a woman's breasts are the size of a small lemon or look like watermelons - most men are keenly interested in them all and love a cleavage. A woman who is attracted to a man is likely to lean forward and bring her arms closer to her body, which presses her breasts together and makes a cleavage.

What do men find attractive in women? Well in the case of breasts it's those of a woman at her sexual and reproductive peak - in her late teens and early twenties. These are typical of the breasts seen in men's magazine centrefolds, on erotic dancers and in advertisements that trade on sex appeal. Researchers at Purdue University in America found that a woman hitchhiker can double the number of lifts she is offered by increasing her bust size by adding 2 inches (5cm) of padding.

Legs

There is a biological reason why men love women's long legs. When a girl reaches puberty, her legs undergo rapid lengthening as hormones flood her body and change her into a woman.
Her extra long legs become a powerful non-verbal signal telling males she is sexually maturing and is now capable of childbearing. This is why legs are often the favourite of many men allowing us to say what men find attractive in women are their legs.
Men love high heels on a woman because it gives her the illusion of having fertile-looking legs. High heels enhance a woman's sexual shape by lengthening her legs, arching her back, forcing her buttocks to protrude, making her feet appear smaller and thrusting her pelvis forward. This is why the shoe with the highest heel — the stiletto - with its bondage straps, is by far the most efficient sex aide on the market.

Most men also prefer a woman with shapely, thicker legs over those with thinner, spindly legs, because additional fat in the legs highlights the sex difference between male and female legs and is an indicator of better lactation. Men like women's legs to look athletic but will be turned off if she has legs like Arnold Schwarzenegger.

WOMEN AND CURVE According to popular belief, a man immediately notice all the curves of a girl. But in fact studies have dimostrto that on average men are attracted to rpincipalmente buttocks and mouth. The legs are long or short does not matter, just shown off in a nice skirt.

So if you’re trying to seduce a man forget the trio: dizzying cleavage, crotch miniskirt and stiletto heels. The first rule of attraction is the right fit, so if I add one thing, I remove the other.

Banned but the bright colors such as blue, yellow, green … Then use your hands to touch his hair and face, will surely be attracted to your donation.
