Like beautiful women, thin waist is slightly different according to different aesthetes, but in general, it can be evaluated by two parameters: absolute waist circumference and waist-hip ratio.

Waist-hip ratio, that is, the ratio of waist circumference to hip circumference, is one of the important indexes to evaluate obesity. The ideal waist-hip ratio should be between 0.85 and 0.95 for men and 0.67 and 0.95 for women. The waist-hip ratio is significantly higher in people with centripetal obesity. When the waist-hip ratio is greater than 1, that is, the waist circumference is greater than the hip circumference, it indicates typical centripetal obesity.

How cruel were the women of the ancient British royal family to themselves for their beauty? Since ancient times, women's waist has always been the key part to highlight exquisite curves and aesthetic feeling, and women with thin waist are often more popular than women with thick waist.

In order to have a "thin waist", how do British royal women do it! On the one hand, women with thin waists look better, and the more important reason is that ancient people thought that women with thin waists usually had a waist-hip ratio of less than 0.8, and they were naturally more fertile and healthier. /kloc-in the 0/9th century, a "thin waist" wind swept across Europe. At that time, women in the British royal family believed that only a thin waist could sway and pose, which could better set off the beauty of the chest and buttocks. Any dignified woman must wear corsets made of wooden boards, whale bones and metal strips. In the 20th century, the trend of girding gradually faded, and women's waistlines returned to a more reasonable size. At present, the waist is still very popular, and there are also some plastic underwear to make the waist look thinner, but mainly comfortable. Writing here, I feel glad that I was born in an era of freedom and peace, and I didn't gird my waist in pursuit of willow slender waist. But for women, having a good figure will be more attractive!
