What are some things you can major in for a career in fashion?

When i grow up I really want to major in Fashion. I would like to go to Fashion Institute Technology in Manhattan, New York. It's been my dream since I was 10 years old. I either want to be a Stylist, Model (cause im really tall) , or in Fashion Marketing. I dont really know all the choices that are out there that revolve around the Fashion Industry. If you know any other "jobs" that involve Fashion please list them for me THANK YOU! Best answer= most detailed!!!!
