Waist–hip ratio
WHR is used as a measurement of obesity, which in turn is a possible indicator of other more serious health conditions. The WHO states that abdominal obesity is defined as a waist-hip ratio above 0.90 for males and above 0.85 for females, or a body mass index (BMI) above 30.0. The National Institute of Diabetes, Digestive and Kidney Diseases (NIDDK) states that women with waist-hip ratios of more than 0.8, and men with more than 1.0, are at increased health risk because of their fat distribution.
Russ Meyer
The Russ Meyer female physical archetype is fairly complex to decipher. Firstly, it's not to be confused with today's surgically enhanced Hollywood porn starlets or even slim, naturally endowed actresses. Russ Meyer was almost as much about a shapely 1950s hip-to-waist ratio or "wasp waist" as he was about very large breasts. The six-pack abdominal muscles and built-up squarish appearance of modern Hollywood figures do not mesh with his pin-up aesthetic. Secondly, he required that even his most busty actresses looked good braless; "gravity-defying" and "cantilevered" became two of his favorite expressions.
