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.
Low-rise pants
Low-rise pants, also known as "hipster jeans", "low-cut jeans", and "lowriders", are a type of pants that sit low on, or below, the hips, usually at least 8 centimetres (3 inches) lower than the navel. Low-rise pants have been available since the 1900s, in styles for both men and women, with popularity increasing in the 2000s.
