All the examples you've brought up are hearsay, but nevertheless, there is a great difference between fashion and the humanities/social sciences, which the OP is looking at studying. The creative arts (fashion, visual arts, music and the like) are one of the few areas where the job prospects are likely so limited that you would seriously want to consider what you wanted to get out of your qualification. Fortunately, most of the people studying creative arts have an extreme passion for what they do, and that's enough for them to make up their minds. And that's fine.
Creative arts degrees teach a very specific set of skills that are only applicable in a few areas, and depending on the institution, have varying degrees of academic rigour. Meanwhile, Arts degrees teach skills which can be applied to a wide range of areas. If you do well in an Arts degree, you'll have enough options open to you. And even if the pay isn't great, so what? You're presumably doing something you enjoy, and you'll at least be making enough money to live in reasonable comfort. The idea that somehow an Arts degree will condemn you to a life of making coffee is simply ludicrous.
