Accessories and clothes are not available for 2D characters. When you create a 3D Head you only get the head itself which is why you then need to dress it up with clothes, hair and other accessories. However, when you create a 2D Head the entire source photo is used including any clothes, hair or accessories that the person is wearing in the photo. Creating a 2D head also has the benefits of being able to animate almost anything. For example, if you want to create a talking orange or apple you can do this by creating a 2D head.
That said we do have some 3D animal heads available. Please see the pack HERE
for some excellent stylized characters from Tokomotion.
