Non-literal. Just close enough that his magic won't really have travel. Like, a T-shirt or Jean jacket won't save you, but a thick winter coat might.

Besides, if he's got any injuries on him at all, clothes aren't really a way to stop him, as he can just form his blood into like, little spikes or something.
