The code for the wardrobe UI is in Assets/avatar-example/UI/Script. The code for the Pen is in Assets/avatar-example/Pen. Additionally, we added HatAvatar.cs and ItemAvatar.cs to Assets/avatar-example for adding hats and handheld items to the avatar and modified TexturedAvatar.cs and FloatingAvatar.cs in the same directory.
