How do you get a Diedrich Sweater anyways??

They were part of the reward tier for using Gaia cash originally, but now you can make them in GoFusion. You can always buy them from the Marketplace or Exchange, too, but they're expensive.

ACK! Those prices are really high xp
I might just um...skip that or quest it later...I barely have enough GoFusion charms to get it but nonetheless, it looks good!
Your cooking is so tough that I'm contemplating starting a shoe company, just to give your overcooked meat some kind of purpose.
