Media and entertainment is not an MBA subject. This belongs to mass communication and journalism. MBA may have, at the most, a second year specialization course on media/film management, that too only in selected IIMs.

Both, mass communication and fashion design has a good scope but you cannot compare both of them as these are totally different fields. Any course turns out to be a great course if you put 100% efforts of yours.
Mass communication deals with journalism, public relations, advertising and media research and much more, whereas fashion designing is all about creative thoughts and how you present them. You should have a very good drawing if you wish to get into fashion designing.
Think again and ponder over the thought that which field interests you the most and then get into it.
