I feel that Fred's look is more of the leather and casual than James. I like to think of the contrast between him and April... "Clean up!" "Why?" "Because you need to; don't you care about how filthy your room is!" "Nah, I'm barely here anyways," he eagled his eyebrows. "Gross! You still need to clean up! Look even James cleans." "Yeah, that's because Mona's coming over later." "I give up, you Fred Weasley are going to die in your own filth and I will dance on your grave!"
