L is a very slim, pale, tall young man with messy neck-length black hair and black eyes. One of his most noticeable features is the shadow below each of his eyes, a result of him being an insomniac. L is always shown to be wearing a pair of blue jeans and a long-sleeved white shirt. He almost never wears shoes or socks, preferring to go barefoot, even while in public. This was shown when he visited Light Yagami's school and was seen barefoot while sitting on a bench.
