As thin as a model, particularly a runway/catwalk model. Very thin with essentially no visible fat. Abdomen is either flat or concave. Hip bones and the lower edges of the rib cage rise above the valley of the abdomen created between them. Real breasts are not present (or at least prominent) as breasts are filled with fat that has been stripped away by calorie deprivation. Small breast "buds," comparable to those of slim girls in the earliest stages of puberty, may be present. Artificial breasts are often present as they are composed of materials that cannot be digested to support metabolism, and the modeling industry seems to prefer them. Cheeks are concave and cheek-bones are prominent. Thighs are not much, if any, thicker than the calves. When the model stands with her feet together, her thighs do not touch each other and she creates the approximation of a one-dimensional line protruding perpendicular to the plane of the floor.
I understand that in order to be model-thin, women must endure constant hunger, hunger-headaches, coldness, frequent colds/flu, and often abuse drugs such as cocaine and cigarettes. Even when they have little body fat, they use laxatives and enemas to minimize their waists. Some force themselves to vomit food they have unintentionally eaten. None the less, I am ashamed to admit that I am enthralled with the sylphic beauty of women who are model thin. I have tried for two decades to ignore or change this attraction, but I cannot shake it.
