The modeling industry is particularly cutthroat, and can have a dangerous impact (beyond malnutrition in models) on the female population at large by presenting society with an image of "perfection" that the majority of women have no hope of ever attaining. 

Female models are generally required to be at least 5' 8" (1,73 m) tall and, according to the AMA, should ideally exhibit the following extreme measurements:

Bust: 34" (86 cm)

Waist: 24" (61 cm)

Hips: 34" (86 cm)
