How to Change Clothes & Appearance in Graveyard Keeper 2

One of the many improvements from the original is that you can now change your clothes and customize the Keeper's appearance in Graveyard Keeper 2. However, it's not clear at first how to do so, and players will find themselves receiving new outfits upon completing quests, but when these are clicked on, they vanish into thin air. Thankfully, they are not deleted, but instead saved for when the player builds a dresser in their new home. It's then possible to change clothes here, as well as the Keeper's hair.
