Fashion marketing or Design&Mgt.?

HI

I really need help guys…i have a bachelor’s degree in a non-design discipline…but i really would like to have degree in design . I want to do a masters degree in design mgt. but many schools require a design background and a portfolio which i do not have. i’am interested in Fashion marketing as well and i’am planning to apply to Parsons school of design in NY.They offer an associate degree in Fashion marketing and bachelor’s degree in Design and Mgt…so is it advisible to do a 4 yrs degree when i already have a bachelor’s degree or should i do an associate degree in fashion marketing? My ultimate goal is to have a masters degree in Design Mgt.
