Fashion Marketing and Marketing in general pays relatively little compared to other fields in the industry. First of all, the quintessence of marketing ( educationally seen) is not very demanding. It depends on the special subjects though. Most students want to have it simple + without mathematics and thus they study fashion marketing with emphasis on 'Fashion Ethics', 'Fashion History', 'Fashion Management' and get through easily. Salary related, they'll get by if they're lucky.
My former human resources prof (he used to be personnell manager of a German large scale enterprise) told me that he received more than 2k applications for only one job advertisement for marketing.
If study fashion marketing with emphasis on logistics, production and statistics etc, your situation on the job market will be totally different (the good kind of 'different') but these subjects are rather demanding and well.... 'dry'. Also note when studying marketing in general, you wil not often be involved in the creative process of an advertisement campaign unless you're lucky.
Thank you, that was very helpful. I know FIT has an undergrad degree for international trade and marketing for the fashion industry which I guess would be a better bet but as you said, dry. I just always hoped to one day work in-house doing marketing for a major fashion brand.
