Honestly, he'll just wear whatever, he's not that picky. Most of his clothes were chosen by either his mother or his sister, both of whom care more about that sort of thing and have better taste than he does. He cares so much about his hair, and he's careful about personal cleanliness, but he's never had to think too much about clothes so he just doesn't.
