In his early twenties with a thin frame and clothes a little too big from him Carl's normal choice of attire matches to wherever he is spending time. The norm is therefore a casual shirt and a pair of jeans with something appropriate to the weather thrown over the top. Slightly below average height with unremarkable features Carl's light brown hair tends to always get to the point where it is past in need of a haircut before he actually does that and the rest of his appearance shares a degree of that disorganisation.
