Being a fashion model takes more than just "standing there" and "looking good". I have known people who worked in the entertainment industry and I know for a fact that preserving your image is something that you must incorporate and intertwine into your own personal life. Things such as fasting for a whole week, eating nothing but fruits and veggies are things I cannot do. Obsessing over your diet in a way that would make anyone else lost sight of common sense is something that people who do this job must possess in order to stay on top of the competition. Also, photo shoot schedules do not run on a normal working timetable so you may be getting home late. The competition is quite cutthroat, and it isn't something that just looking good that qualifies you. You may need a lot of guts in dealing with characters (just like in the ESL industry) and commitment to being excellent. I am sure though the poster whom you are responding to can give good advice on what clothes looks good for many various occasions, which is nothing to sneeze at.
