For high fashion modeling there are size and "look" requirements. Model size seems to be the burning question for many. In checking around I have found no two sources agree on size for fashion models (some agencies have height, weight and size charts they strictly go by and others just a general look) and I am constantly finding exception. Different fashion designer and modeling agencies have varying standard that can change a few inches here and there depending on the "look" for that season (one year they are draping cloths over scare crow thin models, the next they are form fitting over voluptuous models). In general, mainstream female high fashion models are tall, thin, young and beautiful. How tall? Mainstream range - 5'9" to 5'11" with outer fringe being 5'8" to 6" with the extremely rare exception down to 5'5" and as tall as 6'1". Thin - puts weight at 108 to 130lbs in proportional to height. This puts dress size 6-8 with the desired figure around 34B-24-34. This can range some but waist no larger the 25" and maximum hips 35 ½." Beginning models start modeling in the age range of 13-19 and if you have not made it by twenty it is over.
[In checking around it looks like for Fall 2003 they are back to tall and very thin - 5' 9 to 5'10", size 2 to 4 but I think they would love size 0. If you are USA average of 5'6" size 10/12 forget about any hope of being a high fashion model this season.]
In addition to the above numbers there are some general descriptive terms for the "model look." The industry looks for someone who is small to medium boned, fit but not buff. With a long graceful swan like neck, a square jaw and high strong cheek bones. The eyes should be wide set, almond shaped and even, with thick eyelashes. Skin should be clear, small pored, even toned with no scares, tattoos, or piercing. Lips should be medium to full and teeth should be straight and white. Shoulder should be broad and squared and you should have a long legged look (more leg then torso). You should have good posture and be able to carry yourself gracefully. Hair should be healthy and in good condition.
