you only tell you are a fashion student.
If you are student at a University or other higher education institution, and you would like to have advantages like networking with other people/students with higher education, we think the best choice would be MA A-kasse. MA A-kasse has many members within creative fields, like design etc., but only people with high theoretically education.
If you study on a lower level (academy, design school etc) then FTF-A-kasse would be a natural choice. FTF-A has among their members many from within creative practical fields like movie, music, art, design etc.
FTF-A is among the cheapest A-kasser. Off course the price for membership is not relevant as long as you are student - because it is free as long as you are student.
But if you plan to stay in Denmark after you graduate, it is relevant already now to have an good/cheap A-kasse.
