A fine arts background in fashion design, photography, or graphic art would be an excellent supplement to your career as a clothing or makeup stylist. On-the-job training is even more crucial than formal education.
In fact, timing and a good eye for detail— teamed with an assertive disposition and willingness to work long, unpredictable hours—may be enough to land you a financially rewarding and personally fulfilling job. As in most areas within the competitive fashion industry, experience is your best teacher.
Since you will work primarily with photographers and camera operators, set your sights on finding a job in these types of studios. Study and teach yourself what styles blend well together, and visit clothing and accessory stores regularly.
