The Thin Man is a tall, slender being adorned in a black suit and hat, which ominously steeps his eyes in shadow. Like his grayscale wardrobe, his bleak, wrinkled skin is similarly colorless, calling to mind black-and-white films of the 1940s-50s - a possible allusion to his ability to influence televisions. His stature is crooked and misaligned, with cheekbones and closed eyes that appear sunken and emaciated, giving him a corpse-like appearance.

And even though, it may be difficult to see the Thin Man's face, it seems to portray a stoically emotionless expression, when more visible.
