1. The right waist-to-hip ratio
If a woman has wide hips, a man's primal instincts are kicked into gear and he sees that she's fit for childbirth. Researchers found that a ratio of 7:10 is particularly favourable, meaning (as we already know) that men like a small waist with wide child-bearing hips (and probably a booty worthy of the peach emoji to top it off).
2. A high-pitched voice
Having a high-pitched voice signals a smaller, feminine body, as well as youth. Women are most fertile when they're younger – the ages between 20 and 31 are said to be the sage of peak fertility. So don't hold back on those excitable squeals next time someone brings a dog into the office.
3. Healthy hair
Another study found that long, full, shiny hair is extremely attractive. Women with wiry grey hair, for example, are less desirable because they don't look as youthful and therefore fertile as you do with your luscious locks (you don't have to reveal that it's all thanks to your leave-in conditioner and your girl Lisa at the salon who is a DREAM).
4. Less makeup
As much as contouring and a perfectly blended eyeshadow look can totally boost your selfie game, it turns out that a full face of makeup won't help you court a man. The report states that men prefer women who use up to 40 per cent fewer cosmetics.
5. A smile
Naturally, we all prefer to surround ourselves with more positive, happy people. Additionally, the research found that the whiter the teeth on a woman, the better.
6. Wearing red
There are many studies pointing out that wearing red stimulates the senses and enhances attraction. Not only that, but one study found that the colour red can act as a powerful aphrodisiac.
7. Arm length
While – yes – a tall, leggy woman is going to attract admirers, people don't realise that long arms are also a feature that men subtly seek out. Researchers found that men prefer women with longer, more slender arms that had wide girth – probably for hugging and being able to reach the top of cupboards and what not.
8. Overall grooming
A person wearing clean clothes, looking generally groomed and exhibiting good posture has been proved to be another important trait of attraction. It shows that you'll be a good reproductive partner because you're healthy, strong, and ultimately able to look after yourself.
