I did this too.
I think so many people have well, to be honest, tunnel vision when they think that to work in fashion you go to fashion school.
To work in fashion journalism doesn't require going to fashion school - same applies to fashion marketing, fashion buying, etc. It's like saying you want to become a food journalist - you don't
need to go to a cooking school but it is understood that you have a high level of interest in it.
I'm doing a business major also so I can do something in the more business side of fashion

Plus if all else fails, it's something to fall back on.
