Where are my pre-order outfits? (Cozy Grove)

Early in the game (on Day 1 if you complete enough quests), you'll meet Postal Bear. After you complete a quest for him, he'll tell you about your mailbox. The pre-order outfits should be attached to a letter in your mailbox.

• If you don't access your mailbox in the same conversation where Postal Bear first tells you about your mailbox, talk to him again and it should be one of the dialogue options.
