shirt sleeve

noun

1. The part of a shirt that covers an arm.

   “But Dick's necessity of behaving as he did was a projection of some submerged reality: he was compelled to walk there, or stand there, his shirt-sleeve fitting his wrist and his coat sleeve encasing his shirt-sleeve like a sleeve valve, his collar moulded plastically to his neck, his red hair cut exactly, his hand holding his small briefcase like a dandy—just as another man once found it necessary to stand in front of a church in Ferrara, in sackcloth and ashes.”

   “By far the most important fitting issue for sleeves, whether for a woman's shirt or a man's, is length, and that's probably the only part of the shirt sleeve that's bothered you if it wasn't right.”
