Now that she is being forced by her parents at what she doesn't have desires for, her obsession towards her passionate dreams would definitely not let her concentrate on her studies as she keep grumbling that she would dropout of the school somedays if her parents persists she must go to the university.
They say what the old person see while seating, the young won't see it while standing. I believe the parents have more futuristic reasons to want her to be educated. Given that the parents should not be the one to choose a course of study for her but they realise that education shouldn't be relegated in people's lives despite that there are no white collar jobs but to be educated is another assets itself and that is why even the wealthy business men still find out time go back to school after dropping out in their early school days
So in her case too, I believe education is important in person's life. She should look for how to study in fashion courses or related courses so that she will gain better knowledge. The area of her interest can be studied in the university. If someone has opportunity to go to school, let them go because the future is not certain for anyone.
