Of the few things I would go back to school for, fashion isn't one of them. I've met three people in Portland who went to fashion school - they were all working food service with me.
There's a lot of stuff I'd still like to learn before I'm comfortable selling clothes (I'm hoping it will be this coming fall, have lots of free time this summer to make stock), but I feel like a classroom setting isn't necessarily the best place to do that for me. YouTube has been working wonders.
As with many degrees, I know it works for some people, and opens up a lot of doors connection-wise, it's just not for me.
