What is the difference between fashion marketing and fashion merchandising?

Im wondering because i want to be a fashion buyer, like what rachel was in friends, but which would i have to major in fashion marketing or fashion merchandising???

it doesnt really matter they both are the samething if you search for more information on the two you can be a fashion buyer for both of them and also make sure you go to a good school not one that advertise itself on tv late at night those always seem a little sketchy go to top cities like miami, los angelos, new york, chicago and parts of europe..its a risk but its a great career
