At the beginning of the game, you won't be able to. However, we've already seen that you can change your hairstyle and color later on. You probably won't be able to change your skin tone, though, and it's unclear whether colored contacts will be an option.

We've seen people without hats. But we've also seen people with Pangoro hats wearing sunglasses, so I don't understand why you would wear anything else.
