Waist–hip ratio
The waist-hip ratio or waist-to-hip ratio (WHR) is the dimensionless ratio of the circumference of the waist to that of the hips.
This is calculated as waist measurement divided by hip measurement (W ÷ H). For example, a person with a 30″ () waist and 38″ () hips has a waist-hip ratio of about 0.78.
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.
