Who wears the other’s clothes?
I think Kakashi & Iruka both wear each other’s clothes, but for different reasons. Kakashi wears Iruka’s clothes because he tends to just grab the first thing he sees when he’s getting dressed, and if it happens to be Iruka’s uniform, or something else of his, then so be it; and when he later finds out that it’s not his own (because Iruka can tell the difference between their clothes very easily and will let him know) he is always very pleasantly surprised. Even if he doesn’t necessarily go out of his way to wear Iruka’s clothes, he loves being in them.
As for Iruka, he wears Kakashi’s clothes on purpose. He loves being able to smell Kakashi wherever he is, especially when he is away on a mission, because that small hint of his presence makes him feel safe and comforted. That, and his clothes always feel a lot softer and more comfortable than his own – especially his uniform, with all its extra wear; so he’ll go for them any chance he can get.
When Kakashi & Iruka first moved in together, they each had their own separate drawers & hanging space for their clothes; but now the majority of their clothes are mixed together… And they wouldn’t have it any other way 
What do you think?
