Fashion Marketing, but NO Fashion Classes?

I want to go into Fashion Marketing and I am at a relatively good Business school. I love it here and don’t want to leave. But they don’t have a single fashion class on campus. I thought about attending FIT for a year after I graduate and get my AAS in Fashion Design, but I am unsure. I know I want to do Marketing and I want to do Fashion Marketing specifically, but I have no idea how to get my knowledge on the subject.
