OP, if you did an undergraduate degree in art or fashion, you probably would have little or no chance of admission to a master’s program in economics or accounting. However, you quite possibly could gain admission to an MBA program, depending on whether or not you had appropriate preparatory coursework, a good GPA, good GMAT scores, good LORs, appropriate work experience, etc. Appropriate preparatory coursework might include principles of econ, calculus, statistics, and some basic social science courses (e.g., intro psychology and sociology). Employers would focus on your MBA, not your undergrad major. MBA programs don’t presume any particular undergrad major, though to be competitive, you probably would need some demonstration of basic quantitative skills and social science and economic concepts through your undergrad coursework. Perhaps, you’d want to consider a double major, a minor, or a certificate program in business or in a social science or economics. If you had an interest in the business side of art or fashion, going for an MBA might be one pathway you could pursue. Depending on particular interests, other business-related pathways (at the undergrad or graduate level) might include retailing or consumer economics (for fashion), fashion/textile management/marketing (for fashion), arts administration (for art), or nonprofit management (for art).
