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.
T-shirt
A T-shirt typically extends to the waist. Variants of the T-shirt, such as the V-neck, have been developed. Hip hop fashion calls for "tall-T" shirts which may extend down to the knees. A similar item is the T-shirt dress or T-dress, a dress-length T-shirt that can be worn without pants. Long T-shirts are also sometimes worn by women as nightgowns. A 1990s trend in women's clothing involved tight-fitting "cropped" T-shirt or crop tops short enough to reveal the midriff. Another less popular trend is wearing a short-sleeved T-shirt of a contrasting color over a long-sleeved T-shirt, which is known as "layering". T-shirts that are tight to the body are called "fitted", "tailored" or "baby doll" T-shirts.
