The first thing you have to consider is what type of model do you want be? If you are trying for high fashion modeling, the runways of Paris, the cover of Vogue, etc., the requirements are very strict. If you are hoping to do commercial modeling (such as product or lifestyle) the requirements are much broader. If you want to be a glamour, or pin-up model, this area has its own set of requirements.
If you want to be a top fashion model, it only happens in New
York. Fashion modeling does not take place in small town America.
The designers are not there, the fashion magazines are not there,
and the show rooms are not there. The really BIG FASHION happens
in New York and they play by their own rules. If they find you
and you have the look they want for that season, then they have
the photographers, make-up artists, hair stylists, clothing stylists,
art directors, and budgets to make it work. What I am about to
say means very little to the fashion elite. But if you are trying
to get into modeling or you're in a minor fashion market doing
catalog work, character work, product support work, or other secondary
work, then this information holds true.
