Homestead Arcana

New Outfit recipes can be obtained through quests that are received through the mail, then crafted in the Wardrobe. The outfits must be crafted and your starting outfit, the Uniform, doesn't count for the achievement.

This list isn't exhaustive by any means, but here's the ones I've found.
